                     changes in interest rates and, therefore, are subject to the risk of 
                     market price fluctuations. The values of fixed-income securities also 
                     may be affected by changes in the credit rating or financial condition 
                     of the issuing entities. Certain of the tax-exempt securities in which 
                     the Fund may invest without limit may subject certain investors to the 
                     federal, and any applicable state, alternative minimum tax (see page 8).

THE FUND AND ITS MANAGEMENT 
- ----------------------------------------------------------------------------- 


   Morgan Stanley Dean Witter Limited Term Municipal Trust (the "Fund") 
(formerly named Dean Witter Limited Term Municipal Trust) is a no-load, 
open-end, diversified management investment company. The Fund is a trust of 
the type commonly known as a "Massachusetts business trust" and was organized 
under the laws of The Commonwealth of Massachusetts on February 25, 1993. 

   Morgan Stanley Dean Witter Advisors Inc. ("MSDW Advisors" or the 
"Investment Manager"), whose address is Two World Trade Center, New York, New 
York 10048, is the Fund's Investment Manager. The Investment Manager is a 
wholly-owned subsidiary of Morgan Stanley Dean Witter & Co., a preeminent 
global financial services firm that maintains leading market positions in 
each of its three primary businesses--securities, asset management and credit 
services. The Investment Manager, which was incorporated in July, 1992 under 
the name Dean Witter InterCapital Inc., changed its name to Morgan Stanley 
Dean Witter Advisors Inc. on June 22, 1998. 

   MSDW Advisors and its wholly-owned subsidiary, Morgan Stanley Dean Witter 
Services Company Inc., ("MSDW Services"), serve in various investment 
management, advisory, management and administrative capacities to a total of 
101 investment companies, 28 of which are listed on the New York Stock 
Exchange, with combined total assets, including this Fund, of approximately 
$110.3 billion as of May 31, 1998. The Investment Manager also manages 
portfolios of pensions plans, other institutions and individuals which 
aggregated approximately $4.3 billion at such date. 

   The Fund has retained the Investment Manager, pursuant to an Investment 
Management Agreement, to provide administrative services, manage its business 
affairs and manage the investment of the Fund's assets, including the placing 
of orders for the purchase and sale of portfolio securities. MSDW Advisors 
has retained Morgan Stanley Dean Witter Services Company Inc. to perform the 
aforementioned administrative services for the Fund. The Fund's Board of 
Trustees reviews the various services provided by or under the direction of 
the Investment Manager to ensure that the Fund's general investment policies 
and programs are being properly carried out and that administrative services 
are being provided to the Fund in a satisfactory manner. 

   As full compensation for the services and facilities furnished to the Fund 
and for expenses of the Fund assumed by the Investment Manager, the Fund pays 
the Investment Manager monthly compensation calculated daily by applying the 
annual rate of 0.50% to the Fund's net assets determined as of the close of 
each business day. For the fiscal year ended March 31, 1998, the Fund accrued 
total compensation to the Investment Manager amounting to 0.50% of the Fund's 
average daily net assets and the Fund's total expenses amounted to 0.83% of 
the Fund's average daily net assets. 

INVESTMENT OBJECTIVE AND POLICIES 
- ----------------------------------------------------------------------------- 


   The investment objective of the Fund is to provide a high level of current 
income that is exempt from federal income tax, consistent with the 
preservation of capital and prescribed standards of quality and maturity. The 
Fund will seek to achieve its investment objective by investing predominately 
in intermediate term municipal securities. The investment objective is a 
fundamental policy of the Fund and may not be changed without the approval of 
the holders of a majority of the Fund's shares. There is no assurance that 
the Fund's investment objective will be achieved. 

   The Fund will invest at least 75% of its net assets in (a) Municipal Bonds 
which are rated at the time of purchase within the three highest grades by 
Moody's Investors Service, Inc. ("Moody's") or Stan- 

                                5           
<PAGE>

dard & Poor's Corporation ("S&P"); (b) Municipal Notes which at the time of 
purchase are rated in the two highest grades by Moody's or S&P, or, if not 
rated, have outstanding one or more issues of Municipal Bonds rated as set 
forth in clause (a) of this paragraph; and (c) Municipal Commercial Paper 
which at the time of purchase are rated P-1 by Moody's or A-1 by S&P. The 
Fund may also invest up to 25% of its net assets in municipal securities 
rated Baa by Moody's or BBB by S&P, or if not rated, are determined by the 
Investment Manager to be the equivalent of Baa/BBB or better. A description 
of municipal security ratings is contained in the Appendix to the Statement 
of Additional Information. 

   The municipal securities in the Fund's portfolio will have an anticipated 
average dollar-weighted maturity range of 7 to 10 years, with a maximum 
average dollar-weighted maturity of 12 years. However, at least 80% of the 
net assets of the Fund will be subject to an average dollar-weighted maturity 
constraint of 15 years. When computing the average dollar-weighted maturity, 
the Fund intends to treat investments which permit the holder to demand 
payment of principal at any time or at specified intervals prior to the 
stated final maturity as having a maturity equal to the next demand date. The 
final maturity of these demand obligations will be no more than 25 years, 
until such time as the Staff of the Securities and Exchange Commission has 
determined the appropriateness of using maturity shortening techniques for 
obligations with longer final maturities. 

   The foregoing percentage and rating limitations apply at the time of 
acquisition of a security based on the last previous determination of the net 
asset value of the Fund. Any subsequent change in any rating by a rating 
service or change in percentages resulting from market fluctuations or other 
changes in total assets of the Fund will not require elimination of any 
security from the Fund's portfolio. Therefore, the Fund may hold securities 
which have been downgraded from ratings of Baa or BBB or lower by Moody's or 
S&P. However such investments may not exceed 5% of the net assets of the 
Fund. Any investments which exceed this limitation will be eliminated from 
the portfolio within a reasonable period of time (such time as the Investment 
Manager determines that it is practicable to sell the investment without 
undue market or tax consequences to the Fund). Municipal obligations rated 
below investment grade by Moody's or S&P are considered to be speculative 
investments, some of which may not be currently paying any interest and may 
have extremely poor prospects of ever attaining any real investment standing. 

   The two principal classifications of municipal obligations and commercial 
paper are "general obligation" and "revenue" obligations or commercial paper. 
General obligation bonds, notes or commercial paper are secured by the 
issuer's pledge of its faith, credit and taxing power for the payment of 
principal and interest. Issuers of general obligation bonds, notes or 
commercial paper include a state, its counties, cities, towns and other 
governmental units. Revenue bonds, notes or commercial paper are payable from 
the revenues derived from a particular facility or class of facilities or, in 
some cases, from specific revenue sources. Revenue bonds, notes or commercial 
paper are issued for a wide variety of purposes, including the financing of 
electric, gas, water and sewer systems and other public utilities; industrial 
development and pollution control facilities; single and multi-family housing 
units; public buildings and facilities; air and marine ports, transportation 
facilities such as toll roads, bridges and tunnels; and health and 
educational facilities such as hospitals and dormitories. They rely primarily 
on user fees to pay debt service, although the principal revenue source is 
often supplemented by additional security features which are intended to 
enhance the creditworthiness of the issuer's o a governmental unit may be 
pledged to the payment of debt service. In other cases, a special tax or 
other charge may augment user fees. 

   When-Issued and Delayed Delivery Securities and Forward Commitments. From 
time to time, in the ordinary course of business, the Fund may

purchase securities on a when-issued or delayed delivery basis or may 
purchase or sell securities on a forward commitment basis. When such 
transactions are negotiated, the price is fixed at the time of the 
commitment, but delivery and payment can take place a month or more after the 
date of the commitment. There is no overall limit on the percentage of the 
Fund's assets which may be committed to the purchase of securities on a 
when-issued, delayed delivery or forward commitment basis. An increase in the 
percentage of the Fund's assets committed to the purchase of securities on a 
when-issued, delayed delivery or forward commitment basis may increase the 
volatility of the Fund's net asset value. 

   When, As and If Issued Securities. The Fund may purchase securities on a 
"when, as and if issued" basis under which the issuance of the security 
depends upon the occurrence of a subsequent event, such as approval of a 
merger, corporate reorganization, leveraged buyout or debt restructuring. If 
the anticipated event does not occur and the securities are not issued, the 
Fund will have lost an investment opportunity. There is no overall limit on 
the percentage of the Fund's assets which may be committed to the purchase of 
securities on a "when, as and if issued" basis. An increase in the percentage 
of the Fund's assets committed to the purchase of securities on a "when, as 
and if issued" basis may increase the volatility of its net asset value. 

HEDGING ACTIVITIES 

   
   The Fund may enter into financial futures contracts, options on such
futures and municipal bond index futures contracts for hedging purposes.
    

   Financial Futures Contracts and Options on Futures. The Fund may invest in 
financial futures contracts and related options thereon. The Fund may sell a 
financial futures contract or purchase a put option on such futures contract, 
if the Investment Manager anticipates interest rates to rise, as a hedge 
against a decrease in the value of the Funds' portfolio securities. If the 
Investment Manager anticipates that interest rates will decline, the Fund may 
purchase a financial futures contract or a call option thereon to protect 
against an increase in the price of the securities that the Fund intends to 
purchase. These futures contracts and related options thereon will be used 
only as a hedge against anticipated interest rate changes. A futures contract 
sale creates an obligation by the Fund, as seller, to deliver the specific 
type of instrument called for in the contract at a specified future time for 
a specified price. A futures contract purchase would create an obligation by 
the Fund, as purchaser, to take delivery of the specific type of financial 
instrument at a specified future time at a specified price. The specific 
securities delivered or taken, respectively, at settlement date, would not be 
determined until or near that date. The determination would be in accordance 
with the rules of the exchange on which the futures contract sale or purchase 
was effected. 

   Although the terms of financial futures contracts specify actual delivery 
or receipt of securities, in most instances the contracts are closed out 
before the settlement date without the making or taking of delivery of the 
securities. Closing out of a futures contract is effected by entering into an 
offsetting purchase or sale transaction. 

   Unlike a financial futures contract, which requires the parties to buy and 
sell a security on a set date, an option on such a futures contract entitles 
its holder to decide on or before a future date whether to enter into such a 
contract (a long position in the case of a call option and a short position 
in the case of a put option). If the holder decides not to enter into the 
contract, the premium paid for the option on the contract is lost. Since the 
value of the option is fixed at the point of sale, there are no daily 
payments of cash to reflect the change in the value of the underlying 
contract as there is by a purchaser or seller of a futures contract. The 
value of the option does change and is reflected in the net asset value of 
the Fund. 

   Municipal Bond Index Futures. The Fund may utilize municipal bond index 
futures contracts for hedging purposes. The strategies in employing such 
contracts will be similar to that discussed above with 

                                       7
<PAGE>

respect to financial futures and options thereon. A municipal bond index is a 
method of reflecting in a single number the market value of many different 
municipal bonds and is designed to be representative of the municipal bond 
market generally. The index fluctuates in response to changes in the market 
values of the bonds included within the index. Unlike futures contracts on 
particular financial instruments, transactions in futures on a municipal bond 
index will be settled in cash, if held until the close of trading in the 
contract. However, like any other futures contract, a position in the 
contract may be closed out by a purchase or sale of an offsetting contract 
for the same delivery month prior to expiration of the contract. 

   The Fund may not enter into futures contracts or related options thereon 
if, immediately thereafter, the amount committed to margin plus the amount 
paid for option premiums exceeds 5% of the value of the Fund's total assets. 
The Fund may not purchase or sell futures contracts or related options, if, 
immediately thereafter, more than one-third of the net assets of the Fund 
would be hedged. 

   Options. The Fund may purchase or sell (write) options on debt securities 
as a means of achieving additional return or hedging the value of the Fund's 
portfolio. The Fund would only buy options listed on national securities 
exchanges. The Fund will not purchase options on behalf of the Fund if, as a 
result, the aggregate cost of all outstanding options exceeds 10% of the 
Fund's total assets. 

   Lending of Portfolio Securities. The Fund will not lend portfolio 
securities if such loans are not permitted by the laws or regulations of any 
state in which its shares are qualified for sale and will not lend more than 
25% of the value of the total assets of the Fund. 

RISK CONSIDERATIONS 

   Municipal Securities and Ratings. The value of the Fund's portfolio 
securities and, therefore, the Fund's net asset value per share, may increase 
or decrease due to various factors, principally changes in prevailing 
interest rates and the ability of the issuers of the Fund's portfolio 
securities to pay interest and principal on such obligations on a timely 
basis. Generally, a rise in interest rates will result in a decrease in the 
Fund's net asset value per share, while a drop in interest rates will result 
in an increase in the Fund's net asset value per share. 


   Under normal conditions, at least 80% of the total assets of the Fund will 
be invested in securities, the interest on which is exempt from federal 
income taxes. However, the Fund may invest more than 20% of its total assets 
in taxable money market instruments in order to maintain a temporary 
"defensive" position, when, in the opinion of the Investment Manager, 
prevailing market or financial conditions (including unavailability of 
securities of requisite quality) so warrant. Certain of the tax-exempt 
securities in which the Fund may invest without limit may subject certain 
investors to the federal alternative minimum tax or any applicable state 
alternative minimum tax and, therefore, a substantial portion of the income 
produced by the Fund may be taxable to such investors under any federal or 
any applicable state alternative minimum tax. The Fund, therefore, may not be 
a suitable investment for investors who are subject to the alternative 
minimum tax. The suitability of the Fund for these investors will depend upon 
a comparison of the after-tax yield likely to be provided from the Fund to 
comparable tax-exempt investments not subject to such tax and also to 
comparable fully taxable investments in light of each investor's tax 
position. See "Dividends, Distributions and Taxes." 


   Investments in municipal bonds rated either Baa by Moody's or BBB by S&P 
(investment grade bonds--the lowest rated permissible investments by the 
Fund) have speculative characteristics and, therefore, changes in economic 
conditions or other circumstances are more likely to weaken their capacity to 
make principal and interest payments than would be the case with investments 
in securities with higher credit ratings. 

   The ratings assigned by Moody's and S&P represent their opinions as to the 
quality of the securities which they undertake to rate (see the 

                                       8
<PAGE>

Appendix to the Statement of Additional Information). It should be 
emphasized, however, that the ratings are general and not absolute standards 
of quality. 

   Lease Obligations. Included within the revenue bonds category, as noted 
above, are participations in lease obligations or installment purchase 
contracts (hereinafter collectively called "lease obligations") of 
municipalities. State and local governments, agencies or authorities issue 
lease obligations to acquire equipment and facilities. Lease obligations may 
have risks not normally associated with general obligation or other revenue 
bonds. Leases, and installment purchase or conditional sale contracts (which 
may provide for title to the leased asset to pass eventually to the issuer), 
have developed as a means for governmental issuers to acquire property and 
equipment without the necessity of complying with the constitutional and 
statutory requirements generally applicable for the issuance of debt. Certain 
lease obligations contain "non-appropriation" clauses that provide that the 
governmental issuer has no obligation to make future payments under the lease 
or contract unless money is appropriated for such purpose by the appropriate 
legislative body on an annual or other periodic basis. Consequently, 
continued lease payments on those lease obligations containing 
"non-appropriation" clauses are dependent on future legislative actions. If 
such legislative actions do not occur, the holders of the lease obligation 
may experience difficulty in exercising their rights, including disposition 
of the property. 

   In addition, lease obligations represent a relatively new type of 
financing that has not yet developed the depth of marketability associated 
with more conventional municipal obligations, and, as a result, certain of 
such lease obligations may be considered illiquid securities. To determine 
whether or not the Fund will consider such securities to be illiquid (the 
Fund may not invest more than fifteen percent of its net assets in illiquid 
securities), the Trustees of the Fund have established guidelines to be 
utilized by the Fund in determining the liquidity of a lease obligation. The 
factors to be considered in making the determination include: 1) the 
frequency of trades and quoted prices for the obligation; 2) the number of 
dealers willing to purchase or sell the security and the number of other 
potential purchasers; 3) the willingness of dealers to undertake to make a 
market in the security; and 4) the nature of the marketplace trades, 
including the time needed to dispose of the security, the method of 
soliciting offers, and the mechanics of the transfer. 

   Futures Contracts and Options on Futures. A risk in employing futures 
contracts to protect against the price volatility of portfolio securities is 
that the prices of securities subject to such futures contracts may correlate 
imperfectly with the behavior of the cash prices of the Fund's portfolio 
securities. The risk of imperfect correlation will be increased by the fact 
that the financial futures contracts in which the Fund may invest are on 
taxable securities rather than tax-exempt securities, and there is no 
guarantee that the prices of taxable securities will move in a similar manner 
to the prices of tax-exempt securities. The correlation may be distorted by 
the fact that the futures market is dominated by short-term traders seeking 
to profit from the difference between a contract or security price objective 
and their cost of borrowed funds. Such distortions are generally minor and 
would diminish as the contract approached maturity. 

   Another risk is that the Investment Manager could be incorrect in its 
expectations as to the direction or extent of various interest rate movements 
or the time span within which the movements take place. For example, if the 
Fund sold financial futures contracts for the sale of securities in 
anticipation of an increase in interest rates, and then interest rates went 
down instead, causing bond prices to rise, the Fund would lose money on the 
sale. 

   In addition to the risks that apply to all options transactions (see the 
Statement of Additional Information for a description of the characteristics 
of, and the risks of investing in, options on debt securities), there are 
several special risks relating to options on futures. In particular, the 
ability to establish and 

                                       9
<PAGE>

close out positions on such options will be subject to the development and 
maintenance of a liquid secondary market. It is not certain that this market 
will develop or be maintained. 

   Zero Coupon Securities. A portion of the fixed-income securities purchased 
by the Fund may be zero coupon securities. Such securities are purchased at a 
discount from their face amount, giving the purchaser the right to receive 
their full value at maturity. The interest earned on such securities is, 
implicitly, automatically compounded and paid out at maturity. While such 
compounding at a constant rate eliminates the risk of receiving lower yields 
upon reinvestment of interest if prevailing interest rates decline, the owner 
of a zero coupon security will be unable to participate in higher yields upon 
reinvestment of interest received on interest-paying securities if prevailing 
interest rates rise. 

   A zero coupon security pays no interest to its holder during its life. 
Therefore, to the extent the Fund invests in zero coupon securities, it will 
not receive current cash available for distribution to shareholders. In 
addition, zero coupon securities are subject to substantially greater price 
fluctuations during periods of changing prevailing interest rates than are 
comparable securities which pay interest on a current basis. Current federal 
tax law requires that a holder (such as the Fund) of a zero coupon security 
accrue a portion of the discount at which the security was purchased as 
income each year even though the Fund receives no interest payments in cash 
on the security during the year. 


   Year 2000. The investment management services provided to the Fund by the 
Investment Manager and the services provided to shareholders by the 
Distributor and the Transfer Agent depend on the smooth functioning of their 
computer systems. Many computer software systems in use today cannot 
recognize the year 2000, but revert to 1900 or some other date, due to the 
manner in which dates were encoded and calculated. That failure could have a 
negative impact on the handling of securities trades, pricing and account 
services. The Investment Manager, the Distributor and the Transfer Agent have 
been actively working on necessary changes to their own computer systems to 
prepare for the year 2000 and expect that their systems will be adapted 
before that date, but there can be no assurance that they will be successful, 
or that interaction with other non-complying computer systems will not impair 
their services at that time. 

   In addition, it is possible that the markets for securities in which the 
Fund invests may be detrimentally affected by computer failures throughout 
the financial services industry beginning January 1, 2000. Improperly 
functioning trading systems may result in settlement problems and liquidity 
issues. In addition, corporate and governmental data processing errors may 
result in production problems for individual companies and overall economic 
uncertainties. Earnings of individual issuers will be affected by remediation 
costs, which may be substantial. Accordingly, the Fund's investments may be 
adversely affected.

and Policies" section of the Prospectus and to the "Investment Practices and 
Policies" section of the Statement of Additional Information. 

PORTFOLIO MANAGEMENT 


   The Fund's portfolio is actively managed by its Investment Manager with a 
view to achieving the Fund's investment objective. The Fund is managed within 
MSDW Advisors' Tax-Exempt Group, which manages 39 tax-exempt municipal bond 
funds, with approximately $11 billion in assets as of May 31, 1998. Ms. 
Katherine H. Stromberg is the Fund's portfolio manager. Ms. Stromberg has 
been a municipal bond portfolio manager for more than 15 years and has been a 
portfolio manager at MSDW Advisors for over five years. In determining which 
securities to purchase for the Fund or hold in the Fund's portfolio, the 
Investment Manager will rely on information from various sources, including 
research, analysis and appraisals of brokers and dealers, including Dean 
Witter Reynolds Inc., Morgan Stanley & Co. Incorporated and other 
broker-dealers that are affiliates of the Investment Man- 

                                       10

<PAGE>


ager, the views of others regarding economic developments and interest rate 
trends; and the Investment Manager's own analysis of factors it deems 
relevant. 

   Brokerage commissions are not normally charged on the purchase or sale of 
municipal obligations, but such transactions may involve costs in the form of 
spreads between bid and asked prices. Pursuant to an order of the Securities 
and Exchange Commission, the Fund may effect principal transactions in 
certain taxable money market instruments with Dean Witter Reynolds Inc. In 
addition, the Fund may incur brokerage commissions on futures' and options' 
transactions conducted through Dean Witter Reynolds Inc., Morgan Stanley & 
Co. Incorporated and other brokers and dealers that are affiliates of the 
Investment Manager. It is not anticipated that the portfolio trading engaged 
in by the Fund will result in its portfolio turnover rate exceeding 100%. 


INVESTMENT RESTRICTIONS 
- ----------------------------------------------------------------------------- 

   The investment restrictions listed below are among the restrictions, a 
complete listing of which is contained in the Statement of Additional 
Information, which have been adopted by the Fund as fundamental policies. 
Under the Investment Company Act of 1940, as amended (the "Act"), a 
fundamental policy may not be changed without the vote of a majority of the 
outstanding voting securities of the Fund, as defined in the Act. 

   For purposes of the following restrictions: (a) an "issuer" of a security 
is the entity whose assets and revenues are committed to the payment of 
interest and principal on that particular security, provided that the 
guarantee of a security will be considered a separate security and provided 
further that a guarantee of a security shall not be deemed to be a security 
issued by the guarantor if the value of all securities issued or guaranteed 
by the guarantor and owned by the Fund does not exceed 10% of the value of 
the total assets of the Fund; (b) a "taxable security" is any security the 
interest on which is subject to federal income tax; and (c) all percentage 
limitations apply immediately after a purchase or initial investment, and any 
subsequent change in any applicable percentage resulting from market 
fluctuations does not require elimination of any security from the portfolio. 

The Fund may not: 


     1. With respect to 75% of its total assets, purchase securities of any 
    issuer if, immedi ately thereafter, more than 5% of the value of its total 
    assets are in the securities of any one issuer (other than obligations 
    issued, or guaranteed by, the United States Government, its agencies or 
    instrumentalities). 

     2. With respect to 75% of its total assets, purchase more than 10% of all 
    outstanding taxable debt securities of any one issuer (other than debt 
    securities issued, or guaranteed as to principal and interest by, the 
    United States Government, its agencies or instrumentalities). 

     3. Invest 25% or more of the value of its total assets in securities of 
    issuers in any one industry (industrial development and pollution control 
    bonds are grouped into industries based upon the business in which the 
    issuers of such obligations are engaged). This restriction does not apply 
    to obligations issued or guaranteed by the United States Government, its 
    agencies or instrumentalities or to domestic bank obligations. 

   Notwithstanding any other investment policy or restriction, the Fund may 
seek to achieve its investment objective by investing all or substantially 
all of its assets in another investment company having substantially the same 
investment objective and policies as the Fund. 


                                       11

PURCHASE OF FUND SHARES 
- ----------------------------------------------------------------------------- 

   The Fund offers it shares for sale to the pub lic on a continuous basis at 
the offering price with out the imposition of a sales charge. The offering 
price will be the net asset value per share next determined following receipt 
of an order (see "Determination of Net Asset Value"). Pursuant to a 
Distribution Agreement between the Fund and Morgan Stanley Dean Witter 
Distributors Inc. ("MSDW Distributors" or the "Distributor"), an affiliate of 
the Investment Manager, shares of the Fund are distributed by the Distributor 
and are offered by Dean Witter Reynolds Inc. ("DWR"), a selected dealer and 
subsidiary of Morgan Stanley Dean Witter & Co., and other broker-dealers 
which have entered into selected broker-dealer agreements with the 
Distributor ("Selected Broker-Dealers"). It is anticipated that DWR will 
undergo a change of corporate name which is expected to incorporate the brand 
name of "Morgan Stanley Dean Witter," pending approval of various regulatory 
authorities. The principal executive office of the Distributor is located at 
Two World Trade Center, New York, New York 10048. 

   The minimum initial purchase is $1,000 and subsequent purchases of $100 or 
more may be made by sending a check, payable to Morgan Stanley Dean Witter 
Limited Term Municipal Trust, directly to Morgan Stanley Dean Witter Trust 
FSB (the "Transfer Agent" or "MSDW Trust") at P.O. Box 1040, Jersey City, NJ 
07303 or by contacting a Morgan Stanley Dean Witter Financial Advisor or 
other Selected Broker-Dealer representative. The minimum initial purchase in 
the case of investments through EasyInvestSM, an automatic purchase plan (see 
"Shareholder Services"), is $100, provided that the schedule of automatic 
investments will result in investments totalling at least $1,000 within the 
first twelve months. In the case of investments pursuant to Systematic 
Payroll Deduction Plans (including Individual Retirement Plans), the Fund, in 
its discretion, may accept investments without regard to any minimum amounts 
which would otherwise be required if the Fund has reason to believe that 
additional investments will increase the investment in all accounts under 
such Plans to at least $1,000. Certificates for shares purchased will not be 
issued unless a request is made by the shareholder in writing to the Transfer 
Agent. 


   Shares of the Fund are sold through the Distributor or a Selected 
Broker-Dealer on a normal three business day settlement basis; that is, 
payment is due on the third business day (settlement date) after the order is 
placed with the Distributor or Selected Broker-Dealer. Shares of the Fund 
purchased through the Distributor are entitled to dividends beginning on the 
next business day following settlement date. Since DWR or other Selected 
Broker-Dealers forward investors' funds on settlement date, they will benefit 
from the temporary use of the funds if payment is made prior thereto. Shares 
purchased through the Transfer Agent are entitled to dividends beginning on 
the next business day following receipt of an order. As noted above, orders 
placed directly with the Transfer Agent must be accompanied by payment. 
Investors will be entitled to receive capital gains distributions if their 
order is received by the close of business on the day prior to the record 
date for such distributions. Investors will be entitled to receive income 
dividends if their order is received by the close of business on the day 
prior to the record date for such dividends and distributions. 

   Sales personnel of a Selected Broker-Dealer are compensated for shares of 
the Fund sold by them by the Distributor or any of its affiliates and/or by a 
Selected Broker-Dealer. In addition, some sales personnel of the Selected 
Broker-Dealer will receive non-cash compensation as special sales incentives, 
including trips, educational and/or business seminars and merchandise. The 
Fund and the Distributor reserve the right to reject any purchase orders. 

PLAN OF DISTRIBUTION 

   The Fund has entered into a Plan of Distribution pursuant to Rule 12b-1 
under the Act with the Distributor whereby the Distributor is authorized to 

                                       12
<PAGE>


utilize its own resources or those of its affiliates, including MSDW 
Advisors, to finance certain services and activities in connection with the 
distribution of the Fund's shares. The principal activities and services 
which may be provided by the Distributor, DWR, its affiliates and other 
Selected Broker-Dealers under the Plan include: (1) compensation to and 
expenses of Morgan Stanley Dean Witter Financial Advisors and other Selected 
Broker-Dealer representatives and other employees of the Distributor and 
other Selected Broker-Dealers, including overhead and telephone expenses; (2) 
sales incentives and bonuses to sales representatives and to marketing 
personnel in connection with promoting sales of the Fund's shares; (3) 
expenses incurred in connection with promoting sales of the Fund's shares; 
(4) preparing and distributing sales literature; and (5) providing 
advertising and promotional activities, including direct mail solicitation 
and television, radio, newspaper, magazine and other media advertisements. 


DETERMINATION OF NET ASSET VALUE 

   The net asset value per share of the Fund is determined once daily at 4:00 
p.m., New York time (or, on days when the New York Stock Exchange closes 
prior to 4:00 p.m., at such earlier time), on each day that the New York 
Stock Exchange is open by taking the value of all assets of the Fund, 
subtracting all of its respective liabilities, dividing by the number of 
shares outstanding and adjusting to the nearest cent. The net asset value per 
share of the Fund will not be determined on Good Friday and on such other 
federal and non-federal holidays as are observed by the New York Stock 
Exchange. 

   Certain of the Fund's portfolio securities (other than short-term taxable 
debt securities, futures and options) may be valued by an outside independent 
pricing service approved by the Fund's Trustees. The service may utilize a 
computerized grid matrix of tax-exempt securities and evaluations by its 
staff in determining what it believes is the fair value of the Fund's 
portfolio securities. The Board believes that timely and reliable market 
quotations are generally not readily available to the Fund for purposes of 
valuing tax-exempt securities and that the valuations supplied by the pricing 
service are more likely to approximate the fair value of such securities. A 
more detailed discussion of valuation procedures is in the Fund's Statement 
of Additional Information. 

SHAREHOLDER SERVICES 
- ----------------------------------------------------------------------------- 


   Automatic Investment of Dividends and Distributions. All income dividends 
and capital gains distributions are automatically paid in full and fractional 
shares of the Fund (or, if specified by the shareholder, any other open-end 
investment company for which MSDW Advisors serves as investment manager 
(collectively, with the Fund, the "Morgan Stanley Dean Witter Funds")), 
unless the shareholder requests that they be paid in cash. Such dividends and 
distributions will be paid, at the net asset value per share, in shares of 
the Fund (or in cash if the shareholder so requests) on the monthly payment 
date, which will be no later than the last business day of the month for 
which the dividend or distribution is payable. Processing of dividend checks 
begins immediately following the monthly payment date. Shareholders who have 
requested to receive dividends in cash will normally receive their monthly 
dividend check during the first ten days of the following month. 

   EasyInvest (Service Mark). Shareholders may subscribe to EasyInvest, an 
automatic purchase plan which provides for any amount from $100 to $5,000 to 
be transferred automatically from a checking or savings account, or following 
redemption of shares of a Morgan Stanley Dean Witter money market fund, on a 
semi-monthly, monthly or quarterly basis, to the Fund's Transfer Agent for 
investment in shares of the Fund. 


   Systematic Withdrawal Plan. A systematic withdrawal plan (the "Withdrawal 
Plan") is available for shareholders who own or purchase shares of the Fund 
having a minimum value of $10,000 based 

                                       13
<PAGE>

upon the then current net asset value. The Withdrawal Plan provides for 
monthly or quarterly (March, June, September and December) checks in any 
dollar amount, not less than $25, or in any whole percentage of the account 
balance, on an annualized basis. Withdrawal Plan payments should not be 
considered as dividends, yields or income. If periodic withdrawal plan 
payments continuously exceed net investment income and net capital gains, the 
shareholder's original investment could be correspondingly reduced and 
ultimately exhausted. 

   Each withdrawal constitutes a redemption of shares and any gain or loss 
realized must be recognized for federal income, and generally, for state and 
local tax purposes. 


   Shareholders should contact their Morgan Stanley Dean Witter Financial 
Advisor or other Selected Broker-Dealer representative or the Transfer Agent 
for further information about any of the above services. 

   Exchange Privilege.  An "Exchange Privilege," that is, the privilege of 
exchanging shares of certain Morgan Stanley Dean Witter Funds for shares of 
the Fund, exists whereby shares of Morgan Stanley Dean Witter Funds that are 
multiple class funds ("Morgan Stanley Dean Witter Multi-Class Funds"), shares 
of Morgan Stanley Dean Witter Multi-State Municipal Series Trust and Morgan 
Stanley Dean Witter Hawaii Municipal Trust, which are Morgan Stanley Dean 
Witter Funds sold with a front-end sales charge ("FSC Funds"), and shares of 
Morgan Stanley Dean Witter Global Short-Term Income Fund Inc. ("Global 
Short-Term"), which is a Morgan Stanley Dean Witter Fund offered with a 
contingent deferred sales charge ("CDSC"), may be exchanged for shares of the 
Fund, Morgan Stanley Dean Witter Intermediate Term U.S. Treasury Trust, 
Morgan Stanley Dean Witter Short-Term U.S. Treasury Trust and Morgan Stanley 
Dean Witter Short-Term Bond Fund, and for shares of five Morgan Stanley Dean 
Witter Funds which are money market funds: Morgan Stanley Dean Witter Liquid 
Asset Fund Inc., Morgan Stanley Dean Witter U.S. Government Money Market 
Trust, Morgan Stanley Dean Witter Tax-Free Daily Income Trust, Morgan Stanley 
Dean Witter California Tax Free Daily Income Trust and Morgan Stanley Dean 
Witter New York Municipal Money Market Trust (which nine funds, including the 
Fund, are hereinafter collectively referred to as "Exchange Funds"). Shares 
of the Exchange Funds received in an exchange for shares of a Morgan Stanley 
Dean Witter Multi-Class Fund may be redeemed and exchanged only for shares of 
the corresponding Class of a Morgan Stanley Dean Witter Multi-Class Fund or 
for shares of one of the other Exchange Funds, provided that shares of the 
Exchange Funds received in an exchange for Class A shares of a Morgan Stanley 
Dean Witter Multi-Class Fund may also be redeemed and exchanged for shares of 
a FSC Fund, and shares of the Exchange Funds received in an exchange for 
Class B shares of a Morgan Stanley Dean Witter Multi-Class Fund may also be 
redeemed and exchanged for shares of Global Short-Term. In addition, shares 
of the Exchange Funds received in an exchange for shares of a FSC Fund may be 
redeemed and exchanged for Class A shares of a Morgan Stanley Dean Witter 
Multi-Class Fund or for shares of one of the other Exchange Funds, and shares 
of the Exchange Funds received in an exchange for shares of Global Short-Term 
may be redeemed and exchanged for Class B shares of a Morgan Stanley Dean 
Witter Multi-Class Fund or for shares of one of the other Exchange Funds. 

   An exchange to an Exchange Fund that is not a money market fund is on the 
basis of the next calculated net asset value per share of each fund after the 
exchange order is received. When exchanging into a money market fund, shares 
of the Multi-Class Fund, the FSC Fund, Global Short-Term or the Exchange Fund 
are redeemed at their next calculated net asset value and exchanged for 
shares of the money market fund at their net asset value determined the 
following business day. Ultimately, any applicable CDSC will have to be paid 
upon redemption of shares originally purchased from Global Short-Term or a 
Class of a Morgan Stanley Dean Witter Multi-Class Fund that imposes a CDSC. 
(If shares of an Exchange Fund received in ex-

change for shares originally purchased from Global Short-Term or Class B of a 
Morgan Stanley Dean Witter Multi-Class Fund are exchanged for shares of 
Global Short-Term or another Morgan Stanley Dean Witter Multi-Class Fund 
having a different CDSC schedule than that of Global Short-Term or the Morgan 
Stanley Dean Witter Multi-Class Fund from which the Exchange Fund shares were 
acquired, the shares will be subject to the higher CDSC schedule.) During the 
period of time the shares originally purchased from Global Short-Term or from 
a Class of a Morgan Stanley Dean Witter Multi-Class Fund that imposes a CDSC 
remain in the Exchange Fund, the holding period (for the purpose of 
determining the rate of CDSC) is frozen. If those shares are subsequently 
re-exchanged for shares of a Morgan Stanley Dean Witter Multi-Class Fund or 
shares of Global Short-Term, the holding period previously frozen when the 
first exchange was made resumes on the last day of the month in which shares 
of a Morgan Stanley Dean Witter Multi-Class Fund or shares of Global 
Short-Term are reacquired. Thus, the CDSC is based upon the time (calculated 
as described above) the shareholder was invested in shares of a Morgan 
Stanley Dean Witter Multi-Class Fund or in shares of Global Short-Term. In 
the case of exchanges of Class A shares of a Morgan Stanley Dean Witter 
Multi-Class Fund which are subject to a CDSC, the holding period also 
includes the time (calculated as described above) the shareholder was 
invested in shares of a FSC Fund. In the case of shares exchanged into an 
Exchange Fund on or after April 23, 1990, upon a redemption of shares which 
results in a CDSC being imposed, a credit (not to exceed the amount of the 
CDSC) will be given in an amount equal to the Exchange Fund 12b-1 fees, if 
any, incurred on or after that date which are attributable to those shares 
(see "Purchase of Fund Shares--Plan of Distribution" in the respective 
Exchange Fund Prospectus for a description of Exchange Fund distribution 
fees). Exchanges may be made after the shares of the fund acquired by 
purchase (not by exchange or dividend reinvestment) have been held for thirty 
days. There is no waiting period for exchanges of shares acquired by exchange 
or dividend reinvestment. 

   Additional Information Regarding Exchanges. Purchases and exchanges should 
be made for investment purposes only. A pattern of frequent exchanges may be 
deemed by the Distributor to be abusive and contrary to the best interests of 
the Fund's other shareholders and, at the Distributor's discretion, may be 
limited by the Fund's refusal to accept additional purchases and/or exchanges 
from the investor. Although the Fund does not have any specific definition of 
what constitutes a pattern of frequent exchanges, and will consider all 
relevant factors in determining whether a particular situation is abusive and 
contrary to the best interests of the Fund and its other shareholders, 
investors should be aware that the Fund and each of the other Morgan Stanley 
Dean Witter Funds may in their discretion limit or otherwise restrict the 
number of times this Exchange Privilege may be exercised by any investor. Any 
such restriction will be made by the Fund on a prospective basis only, upon 
notice to the shareholder not later than ten days following such 
shareholder's most recent exchange. 

   The Exchange Privilege may be terminated or revised at any time by the 
Fund and/or any of such Morgan Stanley Dean Witter Funds for which shares of 
the Fund may be exchanged, upon such notice as may be required by applicable 
regulatory agencies (presently sixty days' prior written notice for 
termination or material revision), provided that six months' prior written 
notice of termination will be given to the shareholders who hold shares of 
the Exchange Funds pursuant to this Exchange Privilege, and provided further 
that the Exchange Privilege may be terminated or materially revised without 
notice under certain unusual circumstances. Shareholders maintaining margin 
accounts with DWR or another Selected Broker-Dealer are referred to their 
Morgan Stanley Dean Witter Financial Advisor or other Selected Broker-Dealer 
representative regarding restrictions on exchange of shares of the Fund 
pledged in their margin account. 


   The current prospectus for each fund describes its investment objective(s) 
and policies, and shareholders should obtain one and read it carefully before 
investing. Exchanges are subject to the 

                                       15
<PAGE>

minimum investment requirement of each Class of shares and any other 
conditions imposed by each fund. In the case of any shareholder holding a 
share certificate or certificates, no exchanges may be made until all 
applicable share certificates have been received by the Transfer Agent and 
deposited in the shareholder's account. An exchange will be treated for 
federal income tax purposes the same as a repurchase or redemption of shares, 
on which the shareholder may realize a capital gain or loss. However, the 
ability to deduct capital losses on an exchange may be limited in situations 
where there is an exchange of shares within ninety days after the shares are 
purchased. The Exchange Privilege is only available in states where an 
exchange may legally be made. 


   If DWR or another Selected Broker-Dealer is the current broker-dealer of 
record and its account numbers are part of the account information, 
shareholders may initiate an exchange of shares of the Fund for shares of any 
of the above Morgan Stanley Dean Witter Funds pursuant to this Exchange 
Privilege by contacting their Morgan Stanley Dean Witter Financial Advisor or 
other selected Broker-Dealer representative (no Exchange Privilege 
Authorization Form is required). Other shareholders (and those shareholders 
who are clients of DWR or another Selected Broker-Dealer but who wish to make 
exchanges directly by writing or telephoning the Transfer Agent) must 
complete and forward to the Transfer Agent an Exchange Privilege 
Authorization Form, copies of which may be obtained from the Transfer Agent, 
to initiate an exchange. If the Authorization Form is used, exchanges may be 
made by contacting the Transfer Agent at (800) 869-NEWS (toll-free). 


   The Fund will employ reasonable procedures to confirm that exchange 
instructions communicated over the telephone are genuine. Such procedures 
include requiring various forms of personal identification such as name, 
mailing address, social security or other tax identification number and DWR 
or other Selected Broker-Dealer account number (if any). Telephone 
instructions will also be recorded. If such procedures are not employed, the 
Fund may be liable for any losses due to unauthorized or fraudulent 
instructions. 


   Telephone exchange instructions will be accepted if received by the 
Transfer Agent between 9:00 a.m. and 4:00 p.m. New York time, on any day the 
New York Stock Exchange is open. Any shareholder wishing to make an exchange 
who has previously filed an Exchange Privilege Authorization Form and who is 
unable to reach the Fund by telephone should contact his or her Morgan 
Stanley Dean Witter Financial Advisor or other Selected Broker-Dealer 
representative, if appropriate, or make a written exchange request. 
Shareholders are advised that during periods of drastic economic or market 
changes it is possible that the telephone exchange procedures may be 
difficult to implement, although this has not been the experience of the 
Morgan Stanley Dean Witter Funds in the past. 

   For further information regarding the Exchange Privilege, shareholders 
should contact their Morgan Stanley Dean Witter Financial Advisor or other 
Selected Broker-Dealer representative or the Transfer Agent. 


REDEMPTIONS AND REPURCHASES 
- ----------------------------------------------------------------------------- 

   Redemption. Shares of the Fund can be redeemed for cash at any time at its 
respective current net asset value per share (without any redemption or other 
charge). If shares are held in a shareholder's account without a share 
certificate, a written request for redemption is required. If certificates 
are held by the shareholder, the shares may be redeemed by surrendering the 
certificates with a written request for redemption along with any additional 
documentation required by the Transfer Agent, to the Fund's Transfer Agent at 
P.O. Box 983, Jersey City, NJ 07303. 

                                       16
<PAGE>

   Repurchase. DWR and other Selected Broker-Dealers are authorized to 
repurchase shares represented by a share certificate which is delivered to 
any of their offices. Shares held in a shareholder's account without a share 
certificate may also be repurchased by DWR and other Selected Broker-Dealers 
upon the telephonic request of the shareholder. The repurchase price is the 
net asset value next determined (see "Purchase of Fund Shares--Determination 
of Net Asset Value") after such repurchase order is received by DWR and other 
Selected Broker-Dealers. 


   Payment for Shares Redeemed or Repurchased. Payment for shares presented 
for repurchase or redemption will be made by check within seven days after 
receipt by the Transfer Agent of the certificate and/or written request in 
good order. Such payment may be postponed or the right of redemption 
suspended under unusual circumstances. If the shares to be redeemed have 
recently been purchased by check, payment of the redemption proceeds may be 
delayed for the minimum time needed to verify that the check used for 
investment has been honored (not more than fifteen days from the time of 
receipt of the check by the Transfer Agent). Shareholders maintaining margin 
accounts with DWR or another Selected Broker-Dealer are referred to their 
Morgan Stanley Dean Witter Financial Advisor or other Selected Broker-Dealer 
representative regarding restrictions on redemption of shares of the Fund 
pledged in the margin account. 


   Involuntary Redemption. The Fund reserves the right to redeem, on 60 days' 
notice and at net asset value, the shares (other than shares held in an 
Individual Retirement Account or Custodial Account under Section 403(b)(7) of 
the Internal Revenue Code) of any shareholder whose shares have a value of 
less than $100 as a result of redemptions or repurchases, or such lesser 
amount as may be fixed by the Trustees or, in the case of an account opened 
through EasyInvestSM, if after twelve months the shareholder has invested 
less than $1,000 in the account. However, before the Fund redeems such shares 
and sends the proceeds to the shareholder, it will notify the shareholder 
that the value of the shares is less than the applicable amount and allow the 
shareholder sixty days to make an additional investment in an amount which 
will increase the value of his or her account to at least the applicable 
amount before the redemption is processed. 


   Reinstatement Privilege. A shareholder who has had his or her shares 
redeemed or repurchased and has not previously exercised this reinstatement 
privilege may, within thirty days after the date of the redemption or 
repurchase, reinstate any portion or all of the proceeds of such redemption 
or repurchase in shares of a Morgan Stanley Dean Witter Fund at net asset 
value next determined after a reinstatement request, together with the 
proceeds, is received by the Transfer Agent and receive a pro-rata credit for 
any CDSC paid in connection with such redemption or repurchase. 


DIVIDENDS, DISTRIBUTIONS AND TAXES 
- ----------------------------------------------------------------------------- 


   Dividends and Distributions. The Fund declares dividends on each day the 
New York Stock Exchange is open for business. Such dividends are payable 
monthly. The Fund intends to distribute substantially all of its daily net 
investment income on an annual basis. Dividends from net short-term or net 
long-term capital gains, if any, will be paid at least once each year. The 
Fund may, however, determine either to distribute or to retain all or part of 
any net long-term capital gains in any year for reinvestment. Any dividends 
or distributions declared in the last quarter of any calendar year which are 
paid in the following calendar year prior to February 1 will be deemed 
received by the shareholder in the prior calendar year. Shareholders may 
instruct the Transfer Agent (in writing) to have their dividends paid out 
monthly in cash. Processing of dividend checks begins immediately following 
the monthly payment date. Shareholders who have requested to receive 
dividends in cash will normally be sent their monthly dividend check during 
the first ten days of the following month. 


                                       17
<PAGE>

   Taxes. Because the Fund intends to distribute substantially all of its net 
investment income and net capital gains, if any, to shareholders, and intends 
to otherwise comply with all the provisions of Subchapter M of the Internal 
Revenue Code of 1986, as amended (the "Code"), to qualify as a regulated 
investment company ("RIC"), it is not expected that the Fund will be required 
to pay any federal income tax. 


   The Fund intends to qualify to pay "exempt-interest dividends" to its 
shareholders by maintaining, as of the close of each quarter of its taxable 
year, at least 50% of the value of its total assets in tax-exempt securities. 
If the fund qualifies as a RIC and satisfies such requirement, dividends from 
net investment income to shareholders, whether taken in cash or reinvested in 
additional Fund shares, will be excludable from gross income for federal 
income tax purposes to the extent net interest income is represented by 
interest on tax-exempt securities. Exempt-interest dividends are included, 
however, in determining what portion, if any, of a person's Social Security 
benefits are subject to federal income tax. 


   The Code subjects interest received on certain otherwise tax-exempt 
securities to an alternative minimum tax. This alternative minimum tax 
applies to interest received on "private activity bonds" (in general, bonds 
that benefit non-governmental entities) issued after August 7, 1986 which, 
although tax-exempt, are used for purposes other than those generally 
performed by governmental units (e.g., bonds used for commercial or housing 
purposes). Income received on such bonds is classified as a "tax preference 
item," under the alternative minimum tax, for both individual and corporate 
investors. There is no percentage limitation with respect to the Fund's 
investments in such "private activity bonds," with the result that a portion 
of the exempt-interest dividends paid by the Fund may be an item of tax 
preference to shareholders subject to the alternative minimum tax. In 
addition, certain corporations which are subject to the alternative minimum 
tax may have to include a portion of exempt-interest dividends in calculating 
their alternative minimum taxable income in situations where the "adjusted 
current earnings" of the corporation exceeds its alternative minimum taxable 
income. 

   The Fund will mail to shareholders a statement indicating the percentage 
of the dividend distributions for each taxable year which constitutes 
exempt-interest dividends and the percentage, if any, that is taxable, and 
the percentage, if any, of the exempt-interest dividends which constitutes an 
item of tax preference. 

   Shareholders will normally be subject to federal personal income tax on 
market discount on certain taxable and tax-exempt fixed-income securities, 
dividends paid from interest income derived from taxable securities and on 
distributions of net capital gains. For federal income tax purposes, 
distributions of long-term capital gains, if any, are taxable to shareholders 
as long-term capital gains, regardless of how long a shareholder has held the 
Fund's shares and regardless of whether the distribution is received in 
additional shares or cash. To avoid being subject to a 31% backup withholding 
tax on taxable dividends and capital gains distributions and the proceeds of 
redemptions and repurchases, shareholders' taxpayer identification numbers 
must be furnished and certified as to accuracy. Interest on indebtedness 
incurred by shareholders or related parties to purchase or carry shares of an 
investment company paying exempt-interest dividends, such as the Fund, will 
not be deductible by the investor for federal income tax purposes. 

   Under the Revenue Reconciliation Act of 1993, all or a portion of the 
Fund's gain from the sale or redemption of tax-exempt obligations purchased 
at a market discount after April 30, 1993 will be treated as ordinary income 
rather than capital gain. This rule may increase the amount of ordinary 
income dividends received by shareholders. 

   The foregoing relates to federal income taxation as in effect as of the 
date of this Prospectus. Distributions from investment income and capital 
gains, including exempt-interest dividends, may be subject to state franchise 
taxes if received by a 

                                       18
<PAGE>

corporation doing business in various states, and to state and local taxes. 
Shareholders should consult their tax advisers as to the applicability of the 
above to their own tax situation. 

PERFORMANCE INFORMATION 
- ----------------------------------------------------------------------------- 

   From time to time the Fund may quote its "yield" and/or its "total return" 
in advertisements and sales literature. Both the yield and the total return 
of the Fund are based on historical earnings and are not intended to indicate 
future performance. The yield of the Fund is computed by dividing the Fund's 
net investment income over a 30-day period by an average value (using the 
average number of shares entitled to receive dividends and the maximum 
offering price per share at the end of the period), all in accordance with 
applicable regulatory requirements. Such amount is compounded for six months 
and then annualized for a twelve-month period to derive the Fund's yield. The 
Fund may also quote tax-equivalent yield, which is calculated by determining 
the pre-tax yield which, after being taxed at a stated rate, would be 
equivalent to the yield determined as described above. 

   The "average annual total return" of the Fund refers to a figure 
reflecting the average annualized percentage increase (or decrease) in the 
value of an initial investment of $1,000 over periods of one, five and ten 
years, as well as the life of the Fund if less than any of the foregoing. 
Average annual total return reflects all income earned by the Fund, any 
appreciation or depreciation of the Fund's assets and all expenses incurred 
by the Fund for the stated periods. It also assumes reinvestment of all 
dividends and distributions paid by the Fund. 

   In addition to the foregoing, the Fund may advertise its total return over 
different periods of time by means of aggregate, average, year-by-year or 
other types of total return figures. The Fund may also advertise the growth 
of hypothetical investments of $10,000, $50,000 and $100,000 in shares of the 
Fund. The Fund from time to time may also advertise its performance relative 
to certain performance rankings (such as Lipper Analytical Services Inc.) and 
indices compiled by independent organizations (such as the Lehman Brothers 
Municipal Bond Index and Sub-indices). 

ADDITIONAL INFORMATION 
- ----------------------------------------------------------------------------- 

   Voting Rights. All shares of beneficial interest of the Fund are of $0.01 
par value and are equal as to earnings, assets and voting privileges. 

   The Fund is not required to hold Annual Meetings of Shareholders and, in 
ordinary circumstances, the Fund does not intend to hold such meetings. 

   Under Massachusetts law, shareholders of a business trust may, under 
certain circumstances, be held personally liable as partners for obligations 
of the Fund. However, the Declaration of Trust contains an express disclaimer 
of shareholder liability for acts or obligations of the Fund, requires that 
Fund documents include such disclaimer and provides for indemnification and 
reimbursement of expenses out of the Fund's property for any shareholder held 
personally liable for the obligations of the Fund. Thus, the risk of a 
shareholder incurring financial loss on account of shareholder liability is 
limited to circumstances in which the Fund itself would be unable to meet its 
obligations. Given the above limitations on shareholder personal liability 
and the nature of the Fund's assets and operations, the possibility of the 
Fund being unable to meet its obligations is remote and, in the opinion of 
Massachusetts counsel to the Fund, the risk to Fund shareholders of personal 
liability is remote. 


   Code of Ethics. Directors, officers and employees of MSDW Advisors, MSDW 
Services Inc. and 


                                       19
<PAGE>


MSDW Distributors are subject to a strict Code of Ethics adopted by those 
companies. The Code of Ethics is intended to ensure that the interests of 
shareholders and other clients are placed ahead of any personal interest, 
that no undue personal benefit is obtained from a person's employment 
activities and that actual and potential conflicts of interest are avoided. 
To achieve these goals and comply with regulatory requirements, the Code of 
Ethics requires, among other things, that personal securities transactions by 
employees of the companies be subject to an advance clearance process to 
monitor that no Morgan Stanley Dean Witter Fund is engaged at the same time 
in a purchase or sale of the same security. The Code of Ethics bans the 
purchase of securities in an initial public offering, and also prohibits 
engaging in futures and options transactions and profiting on short-term 
trading (that is, a purchase within 60 days of a sale or a sale within 60 
days of a purchase) of a security. In addition, investment personnel may not 
purchase or sell a security for their personal account within 30 days before 
or after any transaction in any Morgan Stanley Dean Witter Fund managed by 
them. Any violations of the Code of Ethics are subject to sanctions, 
including reprimand, demotion or suspension or termination of employment. The 
Code of Ethics comports with regulatory requirements and the recommendations 
in the 1994 report by the Investment Company Institute Advisory Group on 
Personal Investing. 


   Master/Feeder Conversion. The Fund reserves the right to seek to achieve 
its investment objective by investing all of its investable assets in a 
diversified, open-end management investment company having the same 
investment objective and policies and substantially the same investment 
restrictions as those applicable to the Fund. 

   Shareholder Inquiries. All inquiries regarding the Fund should be directed 
to the Fund at the telephone numbers or addresses set forth on the front 
cover of this Prospectus.

   MSDW Advisors also serves as: (i) administrator of The BlackRock Strategic 
Term Trust Inc., a closed-end investment company; (ii) sub-administrator of 
Templeton Global Governments Income Trust, a closed-end investment company; 
and (iii) investment advisor of Offshore Dividend Growth Fund and Offshore 
Money Market Fund, mutual funds established under the laws of the Cayman 
Islands and available only to investors who are participants in DWR's 
International Active Assets Account program and are neither citizens nor 
residents of the United States. 

   Pursuant to an Investment Management Agreement (the "Agreement") with the 
Investment Manager, the Fund has retained the Investment Manager to manage 
the investment of the Fund's assets, including the placing of orders for the 
purchase and sale of portfolio securities. The Investment Manager obtains and 
evaluates such information and advice relating to the economy, securities 
markets, and specific securities as it considers necessary or useful to 
continuously manage the assets of the Fund in a manner consistent with its 
investment objective. 


   Under the terms of the Agreement, in addition to managing the Fund's 
investments, the Investment Manager maintains certain of the Fund's books and 
records and furnishes, at its own expense, such 

                                       5
<PAGE>


office space, facilities, equipment, clerical help and bookkeeping and 
certain legal services as the Fund may reasonably require in the conduct of 
its business, including the preparation of prospectuses, statements of 
additional information, proxy statements and reports required to be filed 
with federal and state securities commissions (except insofar as the 
participation or assistance of independent accountants and attorneys is, in 
the opinion of the Investment Manager, necessary or desirable). In addition, 
the Investment Manager pays the salaries of all personnel, including officers 
of the Fund, who are employees of the Investment Manager. The Investment 
Manager also bears the cost of telephone service, heat, light, power and 
other utilities provided to the Fund. The Investment Manager has retained 
MSDW Services to provide its administrative services under the Agreement. 

   The Fund pays all expenses incurred in its operation. Expenses not 
expressly assumed by the Investment Manager under the Agreement or by Morgan 
Stanley Dean Witter Distributors Inc. ("MSDW Distributors" or the 
"Distributor"), the Distributor of the Fund's shares (see "Purchase of Fund 
Shares") will be paid by the Fund. Such expenses include, but are not limited 
to: charges and expenses of any registrar; custodian, stock transfer and 
dividend disbursing agent; brokerage commissions; taxes; engraving and 
printing of share certificates; registration costs of the Fund and its shares 
under federal and state securities laws; the cost and expense of printing, 
including typesetting, and distributing Prospectuses and Statements of 
Additional Information of the Fund and supplements thereto to the Fund's 
shareholders; all expenses of shareholders' and Trustees' meetings and of 
preparing, printing and mailing of proxy statements and reports to 
shareholders; fees and travel expenses of Trustees or members of any advisory 
board or committee who are not employees of the Investment Manager or any 
corporate affiliate of the Investment Manager; all expenses incident to any 
dividend, withdrawal or redemption options; charges and expenses of any 
outside service used for pricing of the Fund's shares; fees and expenses of 
legal counsel, including counsel to the Trustees who are not interested 
persons of the Fund or of the Investment Manager (not including compensation 
or expenses of attorneys who are employees of the Investment Manager) and 
independent accountants; membership dues of industry associations; interest 
on the Fund's borrowings; postage; insurance premiums on property or 
personnel (including officers and Trustees) of the Fund which inure to its 
benefit; extraordinary expenses including, but not limited to, legal claims 
and liabilities and litigation costs and any indemnification relating thereto 
(depending upon the nature of the legal claim, liability or lawsuit), the 
costs of litigation, payment of legal claims or liabilities or 
indemnification relating thereto; and all other costs of the Fund's 
operations properly payable by the Fund. 

   As full compensation for the services and facilities furnished to the Fund 
and expenses of the Fund assumed by the Investment Manager, the Fund pays the 
Investment Manager monthly compensation calculated daily by applying the 
annual rate of 0.50% to the daily net assets of the Fund. For the fiscal 
years ended March 31, 1996, 1997 and 1998, the Fund accrued to the Investment 
Manager monthly compensation under the Agreement of $401,513, $331,532 and 
$281,962, respectively. 


   The Agreement provides that in the absence of willful misfeasance, bad 
faith, gross negligence or reckless disregard of its obligations thereunder, 
the Investment Manager is not liable to the Fund or any of its investors for 
any act or omission by the Investment Manager or for any losses sustained by 
the Fund or its investors. The Agreement in no way restricts the Investment 
Manager from acting as investment manager or adviser to others. 

   The Investment Manager paid the organizational expenses of the Fund 
incurred prior to the offering of the Fund's shares. The Fund agreed to bear 
and reimburse the Investment Manager for such expenses which totalled 
approximately $140,000. The Fund has deferred and is amortizing these 
organizational expenses on the straight line method over a period not to 
exceed five years from the date of commencement of the Fund's operations. 

   The Agreement was initially approved by the Trustees on February 21, 1997 
and by the shareholders of the Fund at a Special Meeting of Shareholders held 
on May 21, 1997. The Agreement is substantially identical to a prior 
investment management agreement which was initially approved by the Trustees 
on October 30, 1992 and by the shareholders of the Fund at a Special Meeting 
of Shareholders held on January 12, 1993. The Agreement took effect on May 
31, 1997 upon the 

                                       6
<PAGE>

consummation of the merger of Dean Witter, Discover & Co. with Morgan Stanley 
Group Inc. The Agreement may be terminated at any time, without penalty, on 
thirty days' notice by the Board of Trustees of the Fund, by the holders of a 
majority, as defined in the Investment Company Act of 1940 (the "Act"), of 
the outstanding shares of the Fund, or by the Investment Manager. The 
Agreement will automatically terminate in the event of its assignment (as 
defined in the Act). 

   By its terms, the Agreement has an initial term ending April 30, 1999, and 
provides that it will continue from year to year thereafter, provided 
continuance of the Agreement is approved at least annually by the vote of the 
holders of a majority of the outstanding shares of the Fund, as defined in 
the Act, or by the Trustees of the Fund; provided that in either event such 
continuance is approved annually by the vote of a majority of the Trustees of 
the Fund who are not parties to the Agreement or "interested persons" (as 
defined in the Act) of any such party (the "Independent Trustees"), which 
vote must be cast in person at a meeting called for the purpose of voting on 
such approval. 


   The following owned 5% or more of the outstanding shares of beneficial 
interest on June 6, 1998: Doug Rebak, 820 Minsi Trail, Franklin Lakes, NJ, 
07417-2114--6.84%. 

   The Fund has acknowledged that the name "Morgan Stanley Dean Witter" is a 
property right of MSDW. The Fund has agreed that MSDW, or any corporate 
affiliate of MSDW, may use, or at any time permit others to use, the name 
"Morgan Stanley Dean Witter." The Fund has also agreed that in the event the 
investment management contract between the Investment Manager and the Fund is 
terminated, or if the affiliation between MSDW Advisors and its parent 
company is terminated, the Fund will eliminate the name "Morgan Stanley Dean 
Witter" from its name if MSDW, or any corporate affiliate of MSDW, shall so 
request.

THE BOARD OF TRUSTEES, THE INDEPENDENT TRUSTEES, AND THE COMMITTEES 

   The Board of Trustees consists of nine (9) trustees. These same 
individuals also serve as directors or trustees for all of the Morgan Stanley 
Dean Witter Funds, and are referred to in this section as Trustees. As of the 
date of this Statement of Additional Information, there are a total of 86 
Morgan Stanley Dean Witter Funds, comprised of 132 portfolios. As of May 31, 
1998, the Morgan Stanley Dean Witter Funds had total net assets of 
approximately $106 billion and more than six million shareholders. 

   Seven Trustees (77% of the total number) have no affiliation or business 
connection with MSDW Advisors or any of its affiliated persons and do not own 
any stock or other securities issued by MSDW Advisors' parent company, MSDW. 
These are the "disinterested" or "independent" Trustees. Four of the seven 
independent Trustees are also Independent Trustees of the TCW/DW Funds. 

   Law and regulation establish both general guidelines and specific duties 
for the Independent Trustees. The Morgan Stanley Dean Witter Funds seek as 
Independent Trustees individuals of distinction and experience in business 
and finance, government service or academia; these are people whose advice 
and counsel are in demand by others and for whom there is often competition. 
To accept a position on the Funds' Boards, such individuals may reject other 
attractive assignments because the Funds make substantial demands on their 
time. Indeed, by serving on the Funds' Boards, certain Trustees who would 
otherwise be qualified and in demand to serve on bank boards would be 
prohibited by law from doing so. 

   All of the Independent Trustees serve as members of the Audit Committee. 
Three of them also serve as members of the Derivatives Committee. During the 
calendar year ended December 31, 1997, the Audit Committee, the Derivatives 
Committee and the Independent Trustees held a combined total of seventeen 
meetings. 

   The Independent Trustees are charged with recommending to the full Board 
approval of management, advisory and administration contracts, Rule 12b-1 
plans and distribution and underwriting agreements; continually reviewing 
Fund performance; checking on the pricing of portfolio securities, brokerage 
commissions, transfer agent costs and performance, and trading among Funds in 
the same complex; and approving fidelity bond and related insurance coverage 
and allocations, as well as other matters that arise from time to time. The 
Independent Trustees are required to select and nominate individuals to fill 
any Independent Trustee vacancy on the Board of any Fund that has a Rule 
12b-1 plan of distribution. Most of the Morgan Stanley Dean Witter Funds have 
such a plan. 

   The Audit Committee is charged with recommending to the full Board the 
engagement or discharge of the Fund's independent accountants; directing 
investigations into matters within the scope of the independent accountants' 
duties, including the power to retain outside specialists; reviewing with the 
independent accountants the audit plan and results of the auditing 
engagement; approving professional services provided by the independent 
accountants and other accounting firms prior to the performance of such 
services; and reviewing the independence of the independent accountants; 
considering the range of audit and non-audit fees; reviewing the adequacy of 
the Fund's system of internal controls. 

   Finally, the Board of each Fund has formed a Derivatives Committee to 
approve parameters for and monitor the activities of the Fund with respect to 
derivative investments, if any, made by the Fund. 

ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT TRUSTEES FOR ALL MORGAN 
STANLEY DEAN WITTER FUNDS 

   The Independent Trustees and the Funds' management believe that having the 
same Independent Trustees for each of the Morgan Stanley Dean Witter Funds 
avoids the duplication of effort that would arise from having different 
groups of individuals serving as Independent Trustees for each of the Funds 
or even of sub-groups of Funds. They believe that having the same individuals 
serve as Independent 

                                       10
<PAGE>

Trustees of all the Funds tends to increase their knowledge and expertise 
regarding matters which affect the Fund complex generally and enhances their 
ability to negotiate on behalf of each Fund with the Fund's service 
providers. This arrangement also precludes the possibility of separate groups 
of Independent Trustees arriving at conflicting decisions regarding 
operations and management of the Funds and avoids the cost and confusion that 
would likely ensue. Finally, having the same Independent Trustees serve on 
all Fund Boards enhances the ability of each Fund to obtain, at modest cost 
to each separate Fund, the services of Independent Trustees of the caliber, 
experience and business acumen of the individuals who serve as Independent 
Trustees of the Morgan Stanley Dean Witter Funds. 

COMPENSATION OF INDEPENDENT TRUSTEES 

   The Fund pays each Independent Trustee an annual fee of $800 plus a per 
meeting fee of $50 for meetings of the Board of Trustees, the Independent 
Trustees or Committees of the Board of Trustees attended by the Trustee (the 
Fund pays the Chairman of the Audit Committee an additional annual fee of 
$750). If a Board meeting and a meeting of the Independent Trustees or a 
Committee meeting, or a meeting of the Independent Trustees and/or more than 
one Committee meeting, take place on a single day, the Trustees are paid a 
single meeting fee by the Fund. The Fund also reimburses such Trustees for 
travel and other out-of-pocket expenses incurred by them in connection with 
attending such meetings. Trustees who are or have been employed by the 
Investment Manager or an affiliated company receive no compensation or 
expense reimbursement from the Fund for their services as Trustee. Mr. Haire 
currently serves as Chairman of the Audit Committee. Prior to June 1, 1998, 
Mr. Haire also served as Chairman of the Independent Trustees, for which 
services the Fund paid him an additional annual fee of $1,200. 

   The following table illustrates the compensation paid to the Fund's 
Independent Trustees by the Fund for the fiscal year ended March 31, 1998.

services to the 84 Morgan Stanley Dean Witter Funds and, in the case of 
Messrs. Haire, Johnson, Nugent and Schroeder, the 14 TCW/DW Funds that were 
in operation at December 31, 1997. Mr. Haire serves as Chairman of the Audit 
Committee of each Morgan Stanley Dean Witter Fund and each TCW/DW Fund and, 
prior to June 1, 1998, also served as Chairman of the Independent Directors 
or Trustees of those Funds. With respect to Messrs. Haire, Johnson, Nugent 
and Schroeder, the TCW/DW Funds are included solely because of a limited 
exchange privilege between those Funds and five Morgan Stanley Dean Witter 
Money Market Funds. Mr. Hedien's term as Director or Trustee of each Morgan 
Stanley Dean Witter Fund commenced on September 1, 1997.

   As of the date of this Statement of Additional Information, 57 of the 
Morgan Stanley Dean Witter Funds, including the Fund, have adopted a 
retirement program under which an Independent Trustee who retires after 
serving for at least five years (or such lesser period as may be determined 
by the Board) as an Independent Director or Trustee of any Morgan Stanley 
Dean Witter Fund that has adopted the retirement program (each such Fund 
referred to as an "Adopting Fund" and each such Trustee referred to as an 
"Eligible Trustee") is entitled to retirement payments upon reaching the 
eligible retirement age (normally, after attaining age 72). Annual payments 
are based upon length of service. Currently, upon retirement, each Eligible 
Trustee is entitled to receive from the Adopting Fund, commencing as of his 
or her retirement date and continuing for the remainder of his or her life, 
an annual retirement benefit (the "Regular Benefit") equal to 29.41% of his 
or her Eligible Compensation plus 0.4901667% of such Eligible Compensation 
for each full month of service as an Independent Director or Trustee of any 
Adopting Fund in excess of five years up to a maximum of 58.82% after ten 
years of service. The foregoing percentages may be changed by the Board.(1) 
"Eligible Compensation" is one-fifth of the total compensation earned by such 
Eligible Trustee for service to the Adopting Fund in the five year period 
prior to the date of the Eligible Trustee's retirement. Benefits under the 
retirement program are not secured or funded by the Adopting Funds. 


- ------------ 
(1)    An Eligible Trustee may elect alternate payments of his or her 
       retirement benefits based upon the combined life expectancy of such 
       Eligible Trustee and his or her spouse on the date of such Eligible 
       Trustee's retirement. The amount estimated to be payable under this 
       method, through the remainder of the later of the lives of such 
       Eligible Trustee and spouse, will be the actuarial equivalent of the 
       Regular Benefit. In addition, the Eligible Trustee may elect that the 
       surviving spouse's periodic payment of benefits will be equal to either 
       50% or 100% of the previous periodic amount, an election that, 
       respectively, increases or decreases the previous periodic amount so 
       that the resulting payments will be the actuarial equivalent of the 
       Regular Benefit.

INVESTMENT PRACTICES AND POLICIES 
- ----------------------------------------------------------------------------- 

PORTFOLIO SECURITIES 

   Taxable Securities. As discussed in the Prospectus, the Fund may invest up 
to 20% of its total assets in taxable money market instruments, under any one 
of the following circumstances: (a) pending investment of proceeds of the 
sale of the Fund's shares or of portfolio securities, (b) pending settlement 
of purchases of portfolio securities and (c) to maintain liquidity for the 
purpose of meeting anticipated redemptions. 

   In addition, the Fund may temporarily invest more than 20% of its total 
assets in taxable securities, or in tax-exempt securities subject to the 
federal alternative minimum tax for individual shareholders, in order to 
maintain a "defensive" posture when, in the opinion of the Investment 
Manager, it is advisable to do so because of market conditions. The types of 
taxable money market instruments in which the Fund may invest are limited to 
the following short-term fixed-income securities (maturing in one year or 
less from the time of purchase): (i) obligations of the United States 
Government, its agencies, instrumentalities or authorities; (ii) commercial 
paper rated P-1 by Moody's Investors Service, Inc. ("Moody's") or A-1 by 
Standard & Poor's Corporation ("S&P"); (iii) certificates of deposit of 
domestic banks with assets of $1 billion or more; and (iv) repurchase 
agreements with respect to the foregoing portfolio securities. 

   Tax-Exempt Securities. Under normal conditions, at least 80% of the total 
assets of the Fund will be invested in securities, the interest on which is 
exempt from federal income taxes. The tax-exempt securities in which the Fund 
may invest include any or all of the following securities: fixed, variable, 
or floating rate general obligation and revenue bonds (including municipal 
lease obligations and resource recovery bonds); zero coupon and asset-backed 
securities, inverse floaters; tax, revenue, or bond anticipation notes; and 
tax-exempt commercial paper. In regard to the Moody's and S&P ratings 

                                       13
<PAGE>

discussed in the Prospectus, it should be noted that the ratings represent 
the organizations' opinions as to the quality of the securities which they 
undertake to rate and that the ratings are general and not absolute standards 
of quality. For a description of municipal bond, municipal note and municipal 
commercial paper ratings by Moody's and S&P, see the Appendix to this 
Statement of Additional Information. 

   The percentage and rating policies in the Prospectus apply at the time of 
acquisition of a security based upon the last previous determination of the 
Fund's net asset value; any subsequent change in any ratings by a rating 
service or change in percentages resulting from market fluctuations or other 
changes in the amount of total assets will not require elimination of any 
security from the Fund's portfolio until such time as the Investment Manager 
determines that it is practicable to sell the security without undue market 
or tax consequences to the Fund. Therefore, the Fund may hold securities 
which have been downgraded to ratings of Ba or BB or lower by Moody's or S&P. 
Such securities are considered to be speculative investments. 

   Although certain quality standards are applicable at the time of purchase, 
the Fund does not have any minimum quality rating standard for its downgraded 
investments. As such, the Fund may continue to hold securities rated as low 
as Caa, Ca or C by Moody's or CCC, CC, C or CI by S&P. However, such 
investments may not exceed more than 5% of the total assets of the Fund. 
Bonds rated Caa or Ca by Moody's may already be in default on payment of 
interest or principal, while bonds rated C by Moody's, their lowest bond 
rating, can be regarded as having extremely poor prospects of ever attaining 
any real investment standing. Bonds rated CI by S&P, their lowest Bond 
rating, are no longer making interest payments. 

   The payment of principal and interest by issuers of certain municipal 
securities purchased by the Fund may be guaranteed by letters of credit or 
other credit facilities offered by banks or other financial institutions. 
Such guarantees will be considered in determining whether municipal 
securities meet the investment quality requirements of the Fund. In addition, 
some issues may contain provisions which permit the Fund to demand from the 
issuer repayment of principal at some specified period(s) prior to maturity. 

   Municipal Bonds. Municipal bonds, as referred to in the Prospectus, are 
debt obligations of a state, its cities, municipalities and municipal 
agencies (all of which are generally referred to as "municipalities") which 
generally have a maturity at the time of issue of one year or more, and the 
interest from which is, in the opinion of bond counsel to the issuer at time 
of original issuance, exempt from regular federal income tax. These 
obligations are issued to raise funds for various public purposes, such as 
construction of a wide range of public facilities, to refund outstanding 
obligations and to obtain funds for general operating expenses or to loan to 
other public institutions and facilities. In addition, certain types of 
industrial development bonds and pollution control bonds are issued by or on 
behalf of public authorities to provide funding for various privately 
operated facilities. 

   Municipal Notes. Municipal notes are short-term obligations of 
municipalities, generally with a maturity at the time of issuance ranging 
from six months to three years, the interest from which is, in the opinion of 
bond counsel to the issuer at time of original issuance, exempt from regular 
federal income tax. The principal types of municipal notes include tax 
anticipation notes, bond anticipation notes, revenue anticipation notes and 
project notes, although there are other types of municipal notes, in which 
the Fund may invest. Notes sold in anticipation of collection of taxes, a 
bond sale or receipt of other revenues are usually general obligations of the 
issuing municipality or agency. 

   Municipal Commercial Paper. Municipal commercial paper refers to 
short-term obligations of municipalities the interest from which is, in the 
opinion of bond counsel to the issuer at time of original issuance, exempt 
from regular federal income tax. Municipal commercial paper is likely to be 
used to meet seasonal working capital needs of a municipality or interim 
construction financing and to be paid from general revenues of the 
municipality or refinanced with long-term debt. In most cases municipal 
commercial paper is backed by letters of credit, lending agreements, note 
repurchase agreements or other credit facility agreements offered by banks or 
other institutions. 

                                       14
<PAGE>

   The two principal classifications of municipal bonds, notes and commercial 
paper are "general obligation" and "revenue" bonds, notes or commercial 
paper. General obligation bonds, notes or commercial paper are secured by the 
issuer's pledge of its faith, credit and taxing power for the payment of 
principal and interest. Issuers of general obligation bonds, notes or 
commercial paper include a state, its counties, cities, towns and other 
governmental units. Revenue bonds, notes or commercial paper are payable from 
the revenues derived from a particular facility or class of facilities or, in 
some cases, from specific revenue sources. Revenue bonds, notes or commercial 
paper are issued for a wide variety of purposes, including the financing of 
electric, gas, water and sewer systems and other public utilities; industrial 
development and pollution control facilities; single and multi-family housing 
units; public buildings and facilities; air and marine ports; transportation 
facilities such as toll roads, bridges and tunnels; and health and 
educational facilities such as hospitals and dormitories. They rely primarily 
on user fees to pay debt service, although the principal revenue source is 
often supplemented by additional security features which are intended to 
enhance the credit worthiness of the issuer's obligations. In some cases, 
particularly revenue bonds issued to finance housing and public buildings, a 
direct or implied "moral obligation" of a governmental unit may be pledged to 
the payment of debt service. In other cases, a special tax or other charge 
may augment user fees. 

   Issuers of municipal securities are subject to the provisions of 
bankruptcy, insolvency and other laws affecting the rights and remedies of 
creditors, such as the Federal Bankruptcy Act, and laws, if any, which may be 
enacted by Congress or any state extending the time for payment of principal 
or interest, or both, or imposing other constraints upon enforcement of such 
obligations or upon municipalities to levy taxes. There is also the 
possibility that as a result of litigation or other conditions the power or 
ability of any one or more issuers to pay, when due, principal of and 
interest on its, or their, municipal bonds, municipal notes and municipal 
commercial paper may be materially affected. 

   Variable Rate Obligations. As stated in the Prospectus, the Fund may 
invest in obligations of the type called "variable rate obligations." The 
interest rate payable on a variable rate obligation is adjusted either at 
predesignated periodic intervals or whenever there is a change in the market 
rate of interest on which the interest rate payable is based. Other features 
may include the right whereby the Fund may demand prepayment of the principal 
amount of the obligation prior to its stated maturity (a "demand feature") 
and the right of the issuer to prepay the principal amount prior to maturity. 
The principal benefit of a variable rate obligation is that the interest rate 
adjustment minimizes changes in the market value of the obligation. The 
principal benefit to the Fund of purchasing obligations with a demand feature 
is that liquidity, and the ability of the Fund to obtain repayment of the 
full principal amount of the obligation prior to maturity, is enhanced. 

   Zero Coupon Securities. The Fund also may invest in zero coupon securities 
which are debt securities issued or sold at a discount from their face value 
which do not entitle the holder to any periodic payment of interest prior to 
maturity or a specified redemption date (or cash payment date). The amount of 
the discount varies depending on the time remaining until maturity or cash 
payment date, prevailing interest rates, liquidity of the security and 
perceived credit quality of the issuer. Zero coupon securities also may take 
the form of debt securities that have been stripped of their unmatured 
interest coupons, the coupons themselves and receipts or certificates 
representing interests in such stripped debt obligations and coupons. The 
market prices of zero coupon securities generally are more volatile than the 
market prices of interest-bearing securities and are likely to respond to a 
greater degree to changes in interest rates than interest-bearing securities 
having similar maturities and credit qualities. 

   Lending of Portfolio Securities. The Fund may lend portfolio securities to 
brokers, dealers and financial institutions provided that cash equal to at 
least 100% of the market value of the securities loaned is deposited by the 
borrower with the Fund and is maintained each business day in a segregated 
account pursuant to applicable regulations. The collateral value of the 
loaned securities will be marked-to-market daily. While such securities are 
on loan, the borrower will pay the Fund any income accruing thereon, and the 
Fund may invest the cash collateral in portfolio securities, thereby earning 
additional income. The Fund will not lend the portfolio securities if such 
loans are not permitted by the laws or regulations of any state in which its 
shares are qualified for sale and will not lend more than 25% of the value of 
the total assets of the Fund. Loans will be subject to termination by the 
Fund, in the normal 

                                       15
<PAGE>


settlement time, currently five business days after notice, or by the 
borrower on one day's notice. Borrowed securities must be returned when the 
loan is terminated. Any gain or loss in the market price of the borrowed 
securities which occurs during the term of the loan inures to the Fund and 
its shareholders. The Fund may pay reasonable finders, borrowers, 
administrative, and custodial fees in connection with a loan. The 
creditworthiness of firms to which the Fund lends its portfolio securities 
will be monitored on an ongoing basis. During the fiscal year ended March 31, 
1998, the Fund did not loan any of its portfolio securities and it has no 
current intention of doing so in the foreseeable future. 

   When-Issued and Delayed Delivery Securities and Forward Commitments. As 
discussed in the Prospectus, from time to time, in the ordinary course of 
business, the Fund may purchase securities on a when-issued or delayed 
delivery basis and may purchase or sell securities on a forward commitment 
basis. When such transactions are negotiated, the price is fixed at the time 
of the commitment, but delivery and payment can take place a month or more 
after the date of the commitment. The securities so purchased are subject to 
market fluctuation and no interest accrues to the purchaser during this 
period. While the Fund will only purchase securities on a when-issued, 
delayed delivery or forward commitment basis with the intention of acquiring 
the securities, the Fund may sell the securities before the settlement date, 
if it is deemed advisable. At the time the Fund makes the commitment to 
purchase securities on a when-issued or delayed delivery basis, the Fund will 
record the transaction and thereafter reflect the value, each day, of such 
security in determining the net asset value of the Fund. At the time of 
delivery of the securities, the value may be more or less than the purchase 
price. The Fund will also establish a segregated account with the Fund's 
custodian bank in which it will continuously maintain cash or U.S. Government 
securities or other high grade debt portfolio securities equal in value to 
commitments for such when-issued or delayed delivery securities; subject to 
this requirement, the Fund may purchase securities on such basis without 
limit. An increase in the percentage of the Fund's assets committed to the 
purchase of securities on a when-issued or delayed delivery basis may 
increase the volatility of the Fund's net asset value. 

   When, As and If Issued Securities. As discussed in the Prospectus, the 
Fund may purchase securities on a "when, as and if issued" basis under which 
the issuance of the security depends upon the occurrence of a subsequent 
event, such as approval of a merger, corporate reorganization, leveraged 
buyout or debt restructuring. The commitment for the purchase of any such 
security will not be recognized in the portfolio of the Fund until the 
Investment Manager determines that issuance of the security is probable. At 
such time, the Fund will record the transaction and, in determining its net 
asset value, will reflect the value of the security daily. At such time, the 
Fund will also establish a segregated account with its custodian bank in 
which it will continuously maintain cash or U.S. Government securities or 
other liquid portfolio securities equal in value to recognized commitments 
for such securities. Settlement of the trade will occur within five business 
days of the occurrence of the subsequent event. The value of the Fund's 
commitments to purchase the securities of any one issuer, together with the 
value of all securities of such issuer owned by the Fund, may not exceed 5% 
of the value of the Fund's total assets of the time the initial commitment to 
purchase such securities is made (see "Investment Restrictions"). Subject to 
the foregoing restrictions, the Fund may purchase securities on such basis 
without limit. An increase in the percentage of the Fund's assets committed 
to the purchase of securities on a "when, as and if issued" basis may 
increase the volatility of its net asset value. The Fund may also sell 
securities on a "when, as and if issued" basis provided that the issuance of 
the security will result automatically from the exchange or conversion of a 
security owned by the Fund at the time of the sale. 


   Repurchase Agreements. When cash may be available for only a few days, it 
may be invested by the Fund in repurchase agreements until such time as it 
may otherwise be invested or used for payments of obligations of the Fund. 
These agreements, which may be viewed as a type of secured lending by the 
Fund, typically involve the acquisition by the Fund of debt securities from a 
selling financial institution such as a bank, savings and loan association or 
broker-dealer. The agreement provides that the Fund will sell back to the 
institution, and that the institution will repurchase, the underlying 
security ("collateral"), which is held by the Fund's Custodian at a specified 
price and at a fixed time in the future which is usually not more than seven 
days from the date of purchase. The Fund will receive interest from the 
institution until the time when the repurchase is to occur. Although such 
date is deemed by the Fund 

                                       16
<PAGE>


to be the maturity date of a repurchase agreement, the maturities of 
securities subject to repurchase agreements are not subject to any limits and 
may exceed one year. While repurchase agreements involve certain risks not 
associated with direct investments in debt securities, the Fund follows 
procedures designed to minimize such risks. These procedures include 
effecting repurchase transactions only with large, well-capitalized, and 
well-established financial institutions, whose financial condition will be 
continually monitored. In addition, the value of the collateral underlying 
the repurchase agreement will always be at least equal to the repurchase 
price, including any accrued interest earned on the repurchase agreement. In 
the event of a default or bankruptcy by a selling financial institution, the 
Fund will seek to liquidate such collateral. However, the exercising of the 
Fund's right to liquidate such collateral could involve certain costs or 
delays and, to the extent that proceeds from any sale upon a default of the 
obligation to repurchase were less than the repurchase price, the Fund could 
suffer a loss. It is the current policy of the Fund not to invest in 
repurchase agreements that do not mature within seven days if any such 
investment, together with any other illiquid assets held by the Fund, amounts 
to more than 15% of the net assets of the Fund. During the fiscal year ended 
March 31, 1998, the Fund did not enter into repurchase agreements, and it is 
the Fund's current intention not to invest in repurchase agreements in the 
foreseeable future. 


HEDGING ACTIVITIES 

   The Fund may enter into financial futures contracts, options on such 
futures and municipal bond index futures contracts for hedging purposes. 

FUTURES CONTRACT AND OPTIONS ON FUTURES 

   As discussed in the Prospectus, the Fund may invest in financial futures 
contracts ("futures contracts") and related options thereon. These futures 
contracts and related options thereon will be used only as a hedge against 
anticipated interest rate changes. A futures contract sales creates an 
obligation by the Fund, as seller to deliver the specific type of instrument 
called for in the contract at a specified future time for a specified price. 
A futures contract purchase would create an obligation by the Fund, as 
purchaser to take delivery of the specific type of financial instrument at a 
specified future time at a specified price. The specific securities delivered 
or taken, respectively, at settlement date, would not be determined until or 
near that date. The determination would be in accordance with the rules of 
the exchange on which the futures contract sale or purchase was effected. 

   Although the terms of futures contracts specify actual delivery or receipt 
of securities, in most instances the contracts are closed out before the 
settlement date without the making or taking of delivery of the securities. 
Closing out of a futures contract is usually effected by entering into an 
offsetting transaction. An offsetting transaction for a futures contract sale 
is effected by the Fund entering into a futures contract purchase for the 
same aggregate amount of the specific type of financial instrument at the 
same delivery date. If the price in the sale exceeds the price in the 
offsetting purchase, the Fund is immediately paid the difference and thus 
realizes a gain. If the offsetting purchase price exceeds the sale price, the 
Fund pays the difference and realizes the loss. Similarly, the closing out of 
a futures contract purchase is effected by the Fund entering into a futures 
contract sale. If the offsetting sale price exceeds the purchase price, the 
Fund realizes a gain, and if the offsetting sale price is less than the 
purchase price, the Fund realizes a loss. 

   Unlike a futures contract which requires the parties to buy and sell a 
security on a set date, an option on a futures contract entitles its holder 
to decide on or before a future date whether to enter into such a contract. 
If the holder decides not to enter into the contract, the premium paid for 
the option is lost. Since the value of the option is fixed at the point of 
sale, there are no daily payments of cash to reflect the change in the value 
of the underlying contract, as discussed below for futures contracts. The 
value of the option changes and is reflected in the net asset value of the 
Fund. 

   The Fund is required to maintain margin deposits with brokerage firms 
through which it effects futures contracts and options thereon. The initial 
margin requirements vary according to the type of the underlying security. In 
addition, due to current industry practice daily variations in gains and 
losses on 

                                       17
<PAGE>

open contracts are required to be reflected in cash in the form of variation 
margin payments. The Fund may be required to make additional margin payments 
during the term of the contract. 

   Currently, futures contracts can be purchased on debt securities such as 
U.S. Treasury Bills and Bonds, U.S. Treasury Notes with maturities between 6 
1/2 and 10 years, Certificates of the Government National Mortgage 
Association and Bank Certificates of Deposit. The Fund may invest in interest 
rate futures contracts covering these types of financial instruments as well 
as in new types of contracts that become available in the future. 

   Financial futures contracts are traded in an auction environment on the 
floors of several Exchanges -principally, the Chicago Board of Trade, the 
Chicago Mercantile Exchange and the New York Futures Exchange. Each Exchange 
guarantees performance under contract provisions through a clearing 
corporation, a nonprofit organization managed by the Exchange membership 
which is also responsible for handling daily accounting of deposits or 
withdrawals of margin. 

   A risk in employing futures contracts to protect against the price 
volatility of portfolio securities is that the prices of securities subject 
to futures contracts may correlate imperfectly with the behavior of the cash 
prices of the Funds' portfolio securities. The correlation may be distorted 
by the fact that the futures market is dominated by short-term traders 
seeking to profit from the difference between a contract or security price 
objective and their cost of borrowed funds. This would reduce their value for 
hedging purposes over a short time period. The correlation may be further 
distorted since the futures contracts that are being used to hedge are not 
based on municipal obligations. 

   Another risk is that the Fund's Investment Manager could be incorrect in 
its expectations as to the direction or extent of various interest rate 
movements or the time span within which the movements take place. For 
example, if the Fund sold futures contracts for the sale of securities in 
anticipation of an increase in interest rates, and then interest rates went 
down instead, causing bond prices to rise, the Fund would lose money on the 
sale. 

   Put and call options on financial futures have similar characteristics as 
Exchange-traded options. See below for a further description of options. 

   In addition to the risks associated in investing in options on securities, 
there are particular risks associated with investing in options on futures. 
In particular, the ability to establish and close out positions on such 
options will be subject to the development and maintenance of a liquid 
secondary market. It is not certain that this market will develop. 

   In order to assure that the Fund is utilizing futures transactions for 
hedging purposes only, a substantial majority (i.e., approximately 75%) of 
all anticipatory hedge transactions of the Fund (transactions in which the 
Fund does not own at the time of the transaction, but expects to acquire, the 
securities underlying the relevant futures contract) involving the purchase 
of futures contracts or call options thereon will be completed by the 
purchase of securities which are the subject of the hedge. 

   The Fund may not enter into futures contracts or related options thereon 
if immediately thereafter the amount committed to margin of all the Funds' 
futures contracts plus the amount paid for option premiums exceeds 5% of the 
value of the Fund's total assets. In instances involving the purchase of 
futures contracts by the Fund the market value of the futures contract will 
be deposited in a segregated account containing cash and cash equivalents to 
collateralize the position and thereby ensure that the use of such futures is 
unleveraged. The Fund may not purchase or sell futures contracts or related 
options thereon if, immediately thereafter, more than one-third of the Fund's 
net assets would be hedged. 

   Municipal Bond Index Futures. The Fund may utilize municipal bond index 
futures contracts for hedging purposes. The Fund's strategies in employing 
such contracts will be similar to that discussed above with respect to 
financial futures and options thereon. A municipal bond index is a method of 
reflecting in a single number the market value of many different municipal 
bonds and is designed to be representative of the municipal bond market 
generally. The index fluctuates in response to changes in the market values 
of the bonds included within the index. Unlike futures contracts on 
particular financial instruments, transactions in futures on a municipal bond 
index will be settled in cash if held until the close 

                                       18
<PAGE>

of trading in the contract. However, like any other futures contract, a 
position in the contract may be closed out by purchase or sale of an 
offsetting contract for the same delivery month prior to expiration of the 
contract. The Fund's ability to utilize such contracts will be dependent upon 
the development and maintenance of a liquid secondary market for such 
contracts. 

   Options. The Fund may purchase or sell (write) options on debt securities 
as a means of achieving additional return or hedging the value of the Fund's 
portfolio. The Fund would only buy options listed on national securities 
exchanges. The Fund, will not purchase options if, as a result, the aggregate 
cost of all outstanding options exceeds 10% of the Fund's total assets. 

   A call option is a contract that gives the holder of the option the right 
to buy from the writer of the call option, in return for a premium, the 
security underlying the option at a specified exercise price at any time 
during the term of the option. The writer of the call option has the 
obligation upon exercise of the option to deliver the underlying security 
upon payment of the exercise price during the option period. A put option is 
a contract that gives the holder of the option the right to sell to the 
writer, in return for a premium, the underlying security at a specified price 
during the term of the option. The writer of the put has the obligation to 
buy the underlying security upon exercise, at the exercise price during the 
option period. 

   The Fund will only write covered call or covered put options. The Fund may 
not write covered options in an amount exceeding 10% of the value of the 
total assets of the Fund. A call option is "covered" if the Fund owns the 
underlying security subject to the option or has an absolute and immediate 
right to acquire that security or futures contract without additional cash 
consideration (or for additional cash consideration held in a segregated 
account by its custodian) upon conversion or exchange of other securities 
held in its portfolio. A call option is also covered if the Fund holds a call 
on the same security or futures contract as the call written where the 
exercise price of the call held is (i) equal to or less than the exercise 
price of the call written or (ii) greater than the exercise price of the call 
written if the difference is maintained by the Fund in cash, Treasury bills 
or other high grade short-term debt obligations in a segregated account with 
its custodian. A put option is "covered" if the Fund maintains cash, Treasury 
bills or other liquid portfolio securities with a value equal to the exercise 
price in a segregated account with its custodian, or else holds a put on the 
same security or futures contract as the put written where the exercise price 
of the put held is equal to or greater than the exercise price of the put 
written. 

   If the Fund has written an option it may terminate its obligation by 
effecting a closing purchase transaction. This is accomplished by purchasing 
an option of the same series as the option previously written. However, once 
the Fund has been assigned an exercise notice, the Fund will be unable to 
effect a closing purchase transaction. Similarly, if the Fund is the holder 
of an option it may liquidate its position by effecting a closing sale 
transaction. This is accomplished by selling an option of the same series as 
the option previously purchased. There can be no assurance that either a 
closing purchase or sale transaction can be effected when the Fund so 
desires. 

   The Fund will realize a profit from a closing transaction if the price of 
the transaction is less than the premium received from writing the option or 
is more than the premium paid to purchase the option; the Fund, will realize 
a loss from a closing transaction if the price of the transaction is more 
than the premium received from writing the option or is less than the premium 
paid to purchase the option. Since call option prices generally reflect 
increases in the price of the underlying security, any loss resulting from 
the repurchase of a call option may also be wholly or partially offset by 
unrealized appreciation of the underlying security. Other principal factors 
affecting the market value of a put or a call option include supply and 
demand, interest rates, the current market price and price volatility of the 
underlying security and the time remaining until the expiration date. 

   An option position may be closed out only on an exchange which provides a 
secondary market for an option of the same series. Although the Fund will 
generally purchase or write only those options for which there appears to be 
an active secondary market, there is no assurance that a liquid secondary 
market on an exchange will exist for any particular option. In such event it 
might not be possible to effect closing transactions in particular options, 
so that the Fund would have to exercise its options in order to 

                                       19
<PAGE>

realize any profit and would incur brokerage commissions upon the exercise of 
call options and upon the subsequent disposition of underlying securities for 
the exercise of put options. If the Fund as a covered call option writer is 
unable to effect a closing purchase transaction in a secondary market, it 
will not be able to sell the underlying security until the option expires or 
it delivers the underlying security upon exercise. 

PORTFOLIO MANAGEMENT 


   The Fund's portfolio turnover rate during the fiscal year ended March 31, 
1998 was 0%. It is anticipated that the Fund's portfolio turnover rate will 
not exceed 50% during the fiscal year ending March 31, 1999. A 50% turnover 
rate would occur, for example, if 50% of the securities held in the Fund's 
portfolio (excluding all securities whose maturities at acquisition were one 
year or less) were sold and replaced within one year. However, the Fund may 
engage in short-term trading consistent with its investment objective. 
Securities may be sold in anticipation of a market decline (a rise in 
interest rates) or purchased in anticipation of a market rise (a decline in 
interest rates). In addition, a security may be sold and another security of 
comparable quality purchased at approximately the same time to take advantage 
of what the Investment Manager believes to be a temporary disparity in the 
normal yield relationship between the two securities. These yield disparities 
may occur for reasons not directly related to the investment quality of 
particular issues or the general movement of interest rates, such as changes 
in the overall demand for, or supply of, various types of tax-exempt 
securities. 


   In general, purchases and sales may also be made to restructure the 
portfolio in terms of average maturity, quality, coupon yield, or 
diversification for any one or more of the following purposes: (a) to 
increase income, (b) to improve portfolio quality, (c) to minimize capital 
depreciation, (d) to realize gains or losses, or for such other reasons as 
the Investment Manager deems relevant in light of economic and market 
conditions. 

   The Fund does not generally intend to invest more than 25% of its total 
assets in securities of any one governmental unit. Subject to investment 
restriction number 3 in the Prospectus, the Fund may invest more than 25% of 
the total assets in private activity bonds (a certain type of tax-exempt 
municipal security). 

   The Fund may invest up to 15% of its net assets in obligations customarily 
sold to institutional investors in private transactions with the issuers 
thereof and other securities which may be deemed to be illiquid. Due to the 
limited market for certain of these securities, the Fund may be unable to 
dispose of such securities promptly at reasonable prices. It is the current 
intention of the Fund not to invest in such obligations. 

LOCAL GOVERNMENTAL UNIT AND RELATED AUTHORITY OBLIGATIONS 

   Various state statutes authorize local units of government (counties, 
cities, school districts and the like) to issue general obligations and 
revenue obligations, subject to compliance with the requirements of such 
statutes. In addition, various statutes permit local government units to 
organize authorities having the power to issue obligations which are not 
subject to debt limits that may be applicable to the organizing governmental 
unit and which are payable from assets of or revenues derived from projects 
financed by such authorities. Such authorities include parking authorities, 
industrial development authorities, redevelopment authorities, transportation 
authorities, water and sewer authorities, and authorities to undertake 
projects for institutions of higher education and health care. Such 
obligations may generally be affected by adverse changes in the economy of 
the area in which such local government units or projects financed by them or 
by authorities created by them are located, by changes in applicable federal, 
state or local law or regulation, or by changes in levels of federal, state 
or local appropriations, grants or subsidies to the extent such 
appropriations, grants or subsidies directly or indirectly affect revenues of 
such issuers.

INVESTMENT RESTRICTIONS 
- ----------------------------------------------------------------------------- 

   In addition to the investment restrictions enumerated in the Prospectus, 
the investment restrictions listed below have been adopted by the Fund as 
fundamental policies, which may not be changed without the vote of a majority 
of the outstanding voting securities as defined in the Act. Such a majority 
is defined as the lesser of (a) 67% of the shares of the Fund present at a 
meeting of shareholders, if the holders of more than 50% of the outstanding 
shares of the Fund are present or represented by proxy or (b) more than 50% 
of the outstanding shares of the Fund. For purposes of the following 
restrictions and those recited in the Prospectus: (a) an "issuer" of a 
security is the entity whose assets and revenues are committed to the payment 
of interest and principal on that particular security, provided that the 
securities guaranteed by separate entities will be considered a separate 
security and provided further that a guarantee of a security shall not be 
deemed to be a security issued by the guarantor if the value of all 
securities issued or guaranteed by the guarantor and owned by the Fund does 
not exceed 10% of the value of the total assets of the Fund; (b) a "taxable 
security" is any security the interest on which is subject to regular federal 
income tax; and (c) all percentage limitations apply immediately after a 
purchase or initial investment, and any subsequent change in any applicable 
percentage resulting from market fluctuations or other changes in total or 
net assets does not require elimination of any security from the portfolio. 

   The Fund may not: 

      1. Invest in common stock.

      2. Invest in securities of any issuer if, to the knowledge of the Fund,
   any officer or trustee of the Fund or any officer or director of the
   Investment Manager owns more than 1/2 of 1% of the outstanding securities of
   such issuer, and such officers, trustees and directors who own more than 1/2
   of 1% own in the aggregate more than 5% of the outstanding securities of
   such issuer.

      3. Purchase or sell real estate or interests therein (including limited
   partnership interests), although it may purchase securities secured by real
   estate or interests therein.

      4. Purchase or sell commodities except that the Fund may purchase
   financial futures contracts and related options in accordance with
   procedures adopted by the Trustees described in its Prospectus and Statement
   of Additional Information.

      5. Purchase oil, gas or other mineral leases, rights or royalty
   contracts, or exploration or development programs.

      6. Write, purchase or sell puts, calls, or combinations thereof, except
   options on futures contracts or options on debt securities.

      7. Purchase securities of other investment companies, except in
   connection with a merger, consolidation, reorganization or acquisition of
   assets.

      8. Borrow money, except that the Fund may borrow from a bank for
   temporary or emergency purposes in amounts up to 5% (taken at the lower of
   cost or current value) of the value of the total assets of the Fund
   (including the amount borrowed) less its liabilities (not including any
   borrowings but including the fair market value at the time of computation of
   any senior securities then outstanding).

      9. Pledge its assets or assign or otherwise encumber them except to
   secure permitted borrowings. (For the purpose of this restriction,
   collateral arrangements with respect to the writing of options and
   collateral arrangements with respect to initial margin for futures are not
   deemed to be pledges of assets and neither such arrangements nor the
   purchase or sale of futures are deemed to be the issuance of a senior
   security as set forth in restriction 10.)

      10. Issue senior securities as defined in the Act except insofar as the
   Fund may be deemed to have issued a senior security by reason of: (a)
   entering into any repurchase agreement; (b) purchasing any securities on a
   when-issued or delayed delivery basis; or (c) borrowing money in accordance
   with restrictions described above.

                                       21
<PAGE>

      11. Make loans of money or securities, except: (a) by the purchase of
   debt obligations in which the Fund may invest consistent with its investment
   objective and policies; (b) by investment in repurchase agreements; and (c)
   by lending its portfolio securities.

      12. Make short sales of securities.

      13. Purchase securities on margin, except for such short-term loans as
   are necessary for the clearance of purchases of portfolio securities. The
   deposit or payment by the Fund of initial or variation margin in connection
   with futures contracts or related options thereon is not considered the
   purchase of a security on margin.

      14. Engage in the underwriting of securities, except insofar as the Fund
   may be deemed an underwriter under the Securities Act of 1933 in disposing
   of a portfolio security.

      15. Invest for the purpose of exercising control or management of any
   other issuer.

      16. Invest more than 5% of the value of its total assets in securities of
   issuers having a record, together with predecessors, of less than three
   years of continuing operation. This restriction does not apply to
   obligations issued or guaranteed by the United States Government, its
   agencies or instrumentalities.

   Notwithstanding any other investment policy or restriction, the Fund may 
seek to achieve its investment objective by investing all or substantially 
all of its assets in another investment company having substantially the same 
investment objective and policies as the Fund. 

PORTFOLIO TRANSACTIONS AND BROKERAGE 
- ----------------------------------------------------------------------------- 


   The Investment Manager is responsible for decisions to buy and sell 
securities and commodities for the Fund, the selection of brokers and dealers 
to effect the transactions, and the negotiation of brokerage commissions, if 
any. The Fund expects that the primary market for the securities in which it 
intends to invest will generally be the over-the-counter market. Securities 
are generally traded in the over-the-counter market on a "net" basis with 
dealers acting as principal for their own accounts without charging a stated 
commission, although the price of the security usually includes a profit to 
the dealer. Options and futures transactions will usually be effected through 
a broker and a commission will be charged. The Fund also expects that 
securities will be purchased at times in underwritten offerings where the 
price includes a fixed amount of compensation, generally referred to as the 
underwriter's concession or discount. On occasion, the Fund may also purchase 
certain money market instruments directly from an issuer, in which case no 
commissions or discounts are paid. During the fiscal years ended March 31, 
1996, 1997 and 1998, the Fund did not pay any brokerage commissions. 

   The Investment Manager currently serves as investment manager or adviser 
to a number of clients, including other investment companies, and may in the 
future act as investment manager or adviser to others. It is the practice of 
the Investment Manager to cause purchase and sale transactions to be 
allocated among the Fund and others whose assets it manages in such manner as 
it deems equitable. In making such allocations among the Fund and other 
client accounts, various factors may be considered, including the respective 
investment objectives, the relative size of portfolio holdings of the same or 
comparable securities, the availability of cash for investment, the size of 
investment commitments generally held and the opinion of the persons 
responsible for managing the porfolios of the Fund and other client accounts. 
In the case of certain initial and secondary public offerings, the Investment 
Manager utilizes a pro rata allocation process based on the size of the 
Morgan Stanley Dean Witter Funds involved and the number of shares available 
from the public offering. 


   The policy of the Fund, regarding purchases and sales of securities is 
that primary consideration be given to obtaining the most favorable prices 
and efficient execution of transactions. In seeking to implement the Fund's 
policies, the Investment Manager effects transactions with those brokers and 
dealers who the Investment Manager believes provide the most favorable prices 
and are capable of providing efficient executions. If the Investment Manager 
believes such price and executions are obtainable from more than one broker 
or dealer, it may give consideration to placing portfolio 

                                       22
<PAGE>

transactions with those brokers and dealers who also furnish research and 
other services to the Fund or the Investment Manager. Although the Fund may 
purchase securities from brokers or dealers acting as principal, who also 
provide research for the advisor, it will not pay a mark-up in consideration 
for such services. Such services may include, but are not limited to, any one 
or more of the following: information as to the availability of securities 
for purchase or sale; statistical or factual information or opinions 
pertaining to investment; wire services; and appraisals or evaluations of 
portfolio securities. 

   The information and services received by the Investment Manager from 
brokers and dealers may be of benefit to the Investment Manager in the 
management of accounts of some of its other clients and may not, in every 
case, benefit the Fund directly. While the receipt of such information and 
services is useful in varying degrees and would generally reduce the amount 
of research or services otherwise performed by the Investment Manager and 
thereby reduce its expenses, it is of indeterminable value and the Fund will 
not reduce the management fee it pays to the Investment Manager by any amount 
that may be attributable to the value of such services. 

   Pursuant to an order of the Securities and Exchange Commission, the Fund 
may effect principal transactions in certain money market instruments with 
DWR. The Fund will limit its transactions with DWR to U.S. Government and 
Government Agency Securities, Bank Money Instruments (i.e., Certificates of 
Deposit and Bankers' Acceptances) and Commercial Paper. Such transactions 
will be effected with DWR only when the price available from DWR is better 
than that available from other dealers. 


   Consistent with the policy described above, brokerage transactions in 
securities and commodities listed on exchanges or admitted to unlisted 
trading privileges may be effected through DWR, Morgan Stanley & Co. 
Incorporated ("MS & Co.") and other affiliated brokers and dealers. In order 
for an affiliated broker or dealer to effect portfolio transactions for the 
Fund, the commissions, fees or other remuneration received by DWR and MS & 
Co. must be reasonable and fair compared to the commissions, fees or other 
remuneration paid to other brokers in connection with comparable transactions 
involving similar securities being purchased or sold on an exchange during a 
comparable period of time. This standard would allow the affiliated broker or 
dealer to receive no more than the remuneration which would be expected to be 
received by an unaffiliated broker in a commensurate arms-length transaction. 
Furthermore, the Trustees of the Fund, including a majority of the Trustees 
who are not "interested" Trustees, have adopted procedures which are 
reasonably designed to provide that any commissions, fees or other 
remuneration paid to an affiliated broker or dealer are consistent with the 
foregoing standard. During the fiscal years ended March 31, 1996, 1997 and 
1998, the Fund paid no brokerage commissions to DWR. During the period June 
1, 1997 through April 30, 1998, the Fund paid no brokerage commissions to MS 
& Co., which broker-dealer became an affiliate of the Investment Manager on 
May 31, 1997 upon consummation of the merger of Dean Witter, Discover & Co. 
with Morgan Stanley Group Inc. 


PURCHASE OF FUND SHARES 
- ----------------------------------------------------------------------------- 


   As discussed in the Prospectus, the Fund offers its shares for sale to the 
public through Morgan Stanley Dean Witter Distributors Inc. (the 
"Distributor") on a continous basis at an offering price equal to the net 
asset value per share next determined following receipt of any order without 
a sales charge. (See the Prospectus -- "Purchase of Fund Shares.") The 
Distributor has entered into selected broker-dealer agreements with DWR and 
other selected dealers ("Selected Broker-Dealers") pursuant to which shares 
of the Fund are sold. The Distributor, a Delaware corporation, is a 
wholly-owned subsidiary of MSDW. The Trustees who are not, and were not at 
the time they voted, interested persons of the Fund, as defined in the Act 
(the "Independent Trustees"), approved, at their meeting held on April 24, 
1997, the current Distribution Agreement appointing the Distributor as 
exclusive distributor of the Fund's shares and providing for the Distributor 
to bear distribution expenses not borne by the Fund. By its terms, the 
Distribution Agreement has an initial term ending April 30, 1998, and will 
remain in effect from year to year thereafter if approved by the Board. At 
their meeting held on April 30, 1998, the Trustees of the Fund, including a 
majority of the Independent Trustees, approved the continuation of the 
Distribution Agreement. The Distribution Agreement took effect on May 31, 
1997 upon the consummation 


                                       23
<PAGE>

of the merger of Dean Witter, Discover & Co. with Morgan Stanley Group Inc. 
and is substantially identical to the Fund's previous Distribution Agreement 
except for its dates of effectiveness and termination. 


   The Distributor bears all expenses it may incur in providing services 
under the Distribution Agreement. Such expenses include the payment of 
commissions for sales of the Fund's shares and incentive compensation to 
Morgan Stanley Dean Witter Financial Advisors and other Selected 
Broker-Dealer representatives. The Distributor will also pay certain expenses 
in connection with the distribution of the shares of the Fund, including the 
costs of preparing, printing and distributing advertising or promotional 
materials, and the costs of printing and distributing prospectuses and 
supplements thereto used in connection with the offering and sale of the 
Fund's shares. The Fund bears the costs of initial typesetting, printing and 
distribution of prospectuses and supplements thereto to shareholders. The 
Fund also will bear the costs of registering the Fund and its shares under 
federal and state securities laws. The Fund and the Distributor have agreed 
to indemnify each other against certain liabilities, including liabilities 
under the Securities Act of 1933, as amended. Under the Distribution 
Agreement, the Distributor uses its best efforts in rendering services to the 
Fund, but in the absence of willful misfeasance, bad faith, gross negligence 
or reckless disregard of its obligations, the Distributor is not liable to 
the Fund or any of its shareholders for any error of judgment or mistake of 
law or for any act or omission or for any losses sustained by the Fund or its 
shareholders. 


PLAN OF DISTRIBUTION 


   The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under 
the Act (the "Plan") whereby the Distributor or any of its affiliates, 
including MSDW Advisors, is authorized to utilize their own resources to 
finance certain activities in connection with the distribution of shares of 
the Fund. The Plan was approved initially by the Trustees on June 3, 1993, 
and by MSDW Advisors as the Fund's then sole shareholder on June 25, 1993, 
whereupon the Plan went into effect. The vote of the Trustees, which was cast 
in person at a meeting called for the purpose of voting on such Plan, 
included a majority of the Trustees who are not and were not at the time of 
their voting interested persons of the Fund and who have and had at the time 
of their votes no direct or indirect financial interest in the operation of 
the Plan (the "Independent 12b-1 Trustees"). In making their decision to 
adopt the Plan, the Trustees requested from the Distributor and received such 
information as they deemed necessary to make an informed determination as to 
whether or not adoption of the Plan was in the best interests of the 
shareholders of the Fund. After due consideration of the information 
received, the Trustees, including the Independent 12b-1 Trustees, determined 
that adoption of the Plan would benefit the shareholders of the Fund. 

   The Plan provides that the Fund authorizes the Distributor or any of its 
affiliates, including MSDW Advisors, to bear the expense of all promotional 
and distribution related activities on behalf of the Fund. Among the 
activities and services which may be provided under the Plan are: (1) 
compensation to and expenses of Morgan Stanley Dean Witter Financial Advisors 
and other Selected Broker-Dealer representatives and other employees of the 
Distributor and Selected Broker-Dealers, including overhead and telephone 
expenses; (2) sales incentives and bonuses to sales representatives and to 
marketing personnel in connection with promoting sales of the Fund's shares; 
(3) expenses incurred in connection with promoting sales of the Fund's 
shares; (4) preparing and distributing sales literature; and (5) providing 
advertising and promotional activities, including direct mail solicitation 
and television, radio, newspaper, magazine and other media advertisements. 

   Pursuant to the Selected Broker-Dealer Agreements between the Distributor 
and DWR and other Selected Broker-Dealers, the Morgan Stanley Dean Witter 
Financial Advisors and other Selected Broker-Dealer representatives may be 
paid an annual fee based upon the current value of the respective accounts 
for which they are the Financial Advisors or representatives of record. The 
fee also reflects a payment made for expenses associated with the servicing 
of shareholder's accounts, including the expenses of operating branch offices 
in connection with the servicing of shareholder's accounts, which expenses 
include lease costs, the salaries and employee benefits of operations and 
sales support personnel, utility costs, communications costs and the costs of 
stationery and supplies and other expenses relating to branch office 
servicing of shareholder accounts. 


                                       24
<PAGE>

   Under the Plan, the Distributor uses its best efforts in rendering 
services to the Fund, but in the absence of willful misfeasance, bad faith, 
gross negligence or reckless disregard of its obligations, the Distributor is 
not liable to the Fund or any of its shareholders for any error of judgment 
or mistake of law or for any act or omission or for any losses sustained by 
the Fund or its shareholders. 


   At their meeting held April 30, 1998, the Trustees of the Fund, including 
all of the Independent 12b-1 Trustees approved the continuance of the Plan. 
The Plan will remain in effect until April 30, 1999, and from year to year 
thereafter will continue in effect, provided such continuance is approved 
annually by a vote of the Trustees, including a majority of the Independent 
12b-1 Trustees. Assumption by the Fund of any distribution expenses under the 
Plan must be approved by the shareholders, and all material amendments to the 
Plan must be approved by the Trustees in the manner described above. The Plan 
may be terminated at any time, without payment of any penalty, by vote of the 
holders of a majority of the Independent 12b-1 Trustees or by a vote of a 
majority of the outstanding voting securities (as defined in the Act) on not 
more than 30 days' written notice to any other party to the Plan. So long as 
the Plan is in effect, the selection or nomination of the Independent 12b-1 
Trustees is committed to the discretion of the Independent 12b-1 Trustees. 


   Under the Plan, the Distributor provides the Fund, for review by the 
Trustees, and the Trustees review, promptly after the end of each fiscal 
quarter, a written report regarding the distribution expenses incurred by the 
Distributor of the Fund during such fiscal quarter, which report includes (1) 
an itemization of the types of expenses and the purposes therefor; (2) the 
amounts of such expenses; and (3) a description of the benefits derived by 
the Fund. In the Trustees' quarterly review of the Plan they will consider 
its continued appropriateness and the level of compensation provided therein. 


   No interested person of the Fund nor any Trustee of the Fund who is not an 
interested person of the Fund, as defined in the Act, has any direct or 
indirect financial interest in the operation of the Plan except to the extent 
that the Distributor, MSDW Advisors, MSDW Services, DWR or certain of its 
employees may be deemed to have such an interest as a result of benefits 
derived from the successful operation of the Plan or as a result of receiving 
a portion of the amounts expended thereunder by the Distributor or any of its 
affiliates, including MSDW Advisors. 


DETERMINATION OF NET ASSET VALUE 

   As discussed in the Prospectus, portfolio securities (other than 
short-term debt securities and futures and options) are valued for the Fund 
by an outside independent pricing service approved by the Trustees. The 
pricing service has informed the Fund that in valuing the portfolio 
securities, it uses both a computerized grid matrix of tax-exempt securities 
and evaluations by its staff, in each case based on information concerning 
market transactions and quotations from dealers which reflect the bid side of 
the market each day. The portfolio securities are thus valued for the Fund by 
reference to a combination of transactions and quotations for the same or 
other securities believed to be comparable in quality, coupon, maturity, type 
of issue, call provisions, trading characteristics and other features deemed 
to be relevant. The Trustees believe that timely and reliable market 
quotations are generally not readily available to the Fund for purposes of 
valuing tax-exempt securities and that the valuations supplied by the pricing 
service, using the procedures outlined above and subject to periodic review, 
are more likely to approximate the fair value of such securities. Short-term 
taxable debt securities with remaining maturities of 60 days or less at the 
time of purchase are valued at amortized cost, unless the Trustees determine 
such does not reflect the securities' fair value, in which case these 
securities will be valued at their fair value as determined by the Trustees. 
Other short-term taxable debt securities will be valued on a mark to market 
basis until such time as they reach a remaining maturity of 60 days, 
whereupon they will be valued at amortized cost using their value on the 61st 
day unless the Trustees determine such does not reflect the securities' fair 
value, in which case these securities will be valued at their fair value as 
determined by the Trustees. Listed options are valued at the latest sale 
price on the exchange on which they are listed unless no sales of such 
options have taken place that day, in which case they will be valued at the 
mean between their latest bid and asked prices. Unlisted options are valued 
at the mean between their latest bid and asked prices. Futures are valued at 
the latest sale price as of the close of the commodities exchange on which 
they trade unless the Trustees determine that such price does not 

                                       25
<PAGE>

reflect their fair value, in which case they will be valued at their fair 
value as determined by the Trustees. All other securities, including illiquid 
securities, and other assets are valued at their fair value as determined in 
good faith under procedures established by and under the supervision of the 
Trustees. 


   The net asset value per share will be determined once daily at 4:00 p.m. 
New York time (or, on days when the New York Stock Exchange closes prior to 
4:00 p.m., at such earlier time) on each day that the New York Stock Exchange 
is open. The New York Stock Exchange currently observes the following 
holidays: New Year's Day; Reverend Dr. Martin Luther King, Jr. Day; 
Presidents' Day; Good Friday; Memorial Day; Independence Day; Labor Day; 
Thanksgiving Day; and Christmas Day. 


SHAREHOLDER SERVICES 
- ----------------------------------------------------------------------------- 


   Upon the purchase of shares of the Fund, a Shareholder Investment Account 
is opened for the investor on the books of the Fund and maintained by the 
Fund's Transfer Agent, Morgan Stanley Dean Witter Trust FSB (the "Transfer 
Agent"). This is an open account in which shares owned by the investor are 
credited by the Transfer Agent in lieu of issuance of a share certificate. If 
a share certificate is desired, it must be requested in writing for each 
transaction. Certificates are issued only for full shares and may be 
redeposited in the account at any time. There is no charge to the investor 
for issuance of a certificate. Whenever a shareholder instituted transaction 
takes place in the Shareholder Investment Account, the shareholder will be 
mailed a confirmation of the transaction from the Fund or from DWR or another 
Selected Broker-Dealer. 

   Automatic Investment of Dividends and Distributions. Each purchase of 
shares of the Fund is made upon the condition that the Transfer Agent is 
thereby automatically appointed as agent of the investor to receive all 
dividends and distributions on shares owned by the investor. Such dividends 
and distributions will be paid on the monthly payment date, which will be no 
later than the last business day of the month for which the dividend or 
distribution is payable in shares of the Fund at net asset value per share. 
Processing of dividend or distribution checks begins immediately following 
the monthly payment date. Shareholders who have requested to receive 
dividends in cash will normally be sent their monthly dividend check during 
the first ten days of the following month. At any time an investor may 
request the Transfer Agent in writing to have subsequent dividends and/or 
capital gains distributions paid to the investor in cash rather than shares. 
In order to provide sufficient time to process the change, such requests must 
be received by the Transfer Agent at least five business days prior to the 
payment date of the dividend or the record date of the distribution. In case 
of recently purchased shares for which registration instructions have not 
been received on the payment or record date, cash payments will be made to 
the Distributor or the dealer through whom shares were purchased which 
payments will be forwarded to the shareholder, upon receipt of proper 
instructions. It has been and remains the Fund's policy and practice that, if 
checks for dividends or distributions paid in cash remain uncashed, no 
interest will accrue on amounts represented by such uncashed checks. 

   EasyInvest (Service Mark) . Shareholders may subscribe to EasyInvest, an 
automatic purchase plan which provides for any amount from $100 to $5,000 to 
be transferred automatically from a checking or savings account or following 
redemption of shares of a Morgan Stanley Dean Witter money market fund, on a 
semi-monthly, monthly or quarterly basis, to the Transfer Agent for 
investment in shares of the Fund. Shares purchased through EasyInvest will be 
added to the shareholder's existing account at the net asset value calculated 
the same business day the transfer of funds is effected. Shares of the Morgan 
Stanley Dean Witter money market funds redeemed in connection with EasyInvest 
are redeemed on the business day preceding the transfer of funds. For further 
information or to subscribe to EasyInvest, shareholders should contact their 
Morgan Stanley Dean Witter Financial Advisor or other Selected Broker-Dealer 
representative or the Transfer Agent. 


   Systematic Withdrawal Plan. As discussed in the Prospectus, a withdrawal 
plan is available for shareholders who own or purchase shares of the Fund 
having a minimum value of $10,000 based upon the then current offering price. 
The plan provides for monthly or quarterly (March, June, September and 
December) checks in any dollar amount, not less than $25, or in any whole 
percentage of the account balance, on an annualized basis. 

                                       26
<PAGE>

   Dividends and capital gains distributions on shares held under the 
Systematic Withdrawal Plan will be invested in additional full and fractional 
shares at net asset value (without a sales charge). Shares will be credited 
to an open account for the investor by the Transfer Agent; no share 
certificates will be issued. A shareholder is entitled to a share certificate 
upon written request to the Transfer Agent, although in that event the 
shareholder's Systematic Withdrawal Plan will be terminated. 

   The Transfer Agent acts as agent for the shareholder in tendering to the 
Fund for redemption sufficient full and fractional shares to provide the 
amount of the periodic withdrawal payment designated in the application. The 
shares will be redeemed at their net asset value determined, at the 
shareholder's option on the tenth or twenty-fifth day (or next following 
business day) of the relevant month or quarter and normally a check for the 
proceeds will be mailed by the Transfer Agent, or amounts credited to a 
shareholder's DWR or other selected broker-dealer brokerage account within 
five business days after the date of redemption. The Withdrawal Plan may be 
terminated at any time by the Fund. 

   Withdrawal Plan payments should not be considered as dividends, yields or 
income. If periodic withdrawal plan payments continuously exceed net 
investment income and net capital gains, the shareholder's original 
investment will be correspondingly reduced and ultimately exhausted. Each 
withdrawal constitutes a redemption of shares and any gain or loss realized 
must be recognized for federal income tax purposes. 

   Any shareholder who wishes to have payments under the Withdrawal Plan made 
to a third party or sent to an address other than the one listed on the 
account must send complete written instructions to the Transfer Agent to 
enroll in the Withdrawal Plan. The shareholder's signature on such 
instructions must be guaranteed by an eligible guarantor acceptable to the 
Transfer Agent (shareholders should contact the Transfer Agent for a 
determination as to whether a particular institution is such an eligible 
guarantor). A shareholder may, at any time change the amount and interval of 
withdrawal payments and the address to which checks are mailed through his or 
her account executive or by written notification to the Transfer Agent. The 
shareholder's signature on such notification must be guaranteed by an 
eligible guarantor as described above. The shareholder may also terminate the 
Systematic Withdrawal Plan at any time by written notice to the Transfer 
Agent. In the event of such termination, the account will becontinued as a 
Shareholder Investment Account. The shareholder may also redeem all or part 
of the shares held in the Systematic Withdrawal Plan account (see 
"Redemptions and Repurchases" in the Prospectus) at any time. Shareholders 
wishing to enroll in the Withdrawal Plan should contact their account 
executive or the Transfer Agent. 


   Targeted Dividends (Service Mark) . In states where it is legally 
permissible, shareholders may also have all income dividends and capital 
gains distributions automatically invested in shares of any open-end Morgan 
Stanley Dean Witter Fund other than Morgan Stanley Dean Witter Limited Term 
Municipal Trust. Such investment will be made at the net asset value per 
share (without sales charge) of the selected Morgan Stanley Dean Witter Fund 
as of the close of business on the payment date of the dividend or 
distribution, and will begin to earn dividends, if any, in the selected 
Morgan Stanley Dean Witter Fund the next business day. Shareholders of the 
Fund must be shareholders of the Morgan Stanley Dean Witter Fund targeted to 
receive investments from dividends and distributions at the time they enter 
the Targeted Dividend program. Nevertheless, investors should review the 
prospectus of the targeted Morgan Stanley Dean Witter Fund before entering 
the program. 

   Direct Investments through Transfer Agent. As discussed in the Prospectus, 
a shareholder may make additional investments in Fund shares at any time 
through the Shareholder Investment Account by sending a check in any amount, 
not less than $100, payable to Morgan Stanley Dean Witter Limited Term 
Municipal Trust, directly to the Fund's Transfer Agent. The investment 
proceeds will be applied to the purchase of shares of the Fund at the net 
asset value per share next computed after receipt of the check or purchase 
payment by the Transfer Agent. The shares so purchased will be credited to 
the investor's account. 


   Tax-Sheltered Retirement Plans. Retirement plans are available for use by 
corporations, the self-employed, Individual Retirement Accounts and Custodial 
Accounts under Section 403(b)(7) of the Internal Revenue Code. Adoption of 
such plans should be on advice of legal counsel or tax adviser. 

                                       27
<PAGE>


   For further information regarding plan administration, custodial fees and 
other details, investors should contact their Morgan Stanley Dean Witter 
Financial Advisor or other Selected Broker-Dealer representative or the 
Transfer Agent. 

   Exchange Privilege. As discussed in the Prospectus under the caption 
"Exchange Privilege," an Exchange Privilege exists whereby investors who have 
purchased shares of any of the Morgan Stanley Dean Witter Funds that are 
multiple class funds ("Morgan Stanley Dean Witter Multi-Class Funds"), shares 
of Morgan Stanley Dean Witter Multi-State Municipal Series Trust and Morgan 
Stanley Dean Witter Hawaii Municipal Trust, which are Morgan Stanley Dean 
Witter Funds sold with a front-end sales charge ("FSC Funds"), and shares of 
Morgan Stanley Dean Witter Global Short-Term Income Fund Inc. ("Global 
Short-Term"), which is a Morgan Stanley Dean Witter Fund offered with a 
contingent deferred sales charge ("CDSC"), will be permitted, after the 
shares of the fund acquired by purchase (not by exchange or dividend 
reinvestment) have been held for thirty days, to redeem all or part of their 
shares in that fund, have the proceeds invested in shares of the Fund, Morgan 
Stanley Dean Witter Intermediate Term U.S. Treasury Trust, Morgan Stanley 
Dean Witter Short-Term U.S. Treasury Trust and Morgan Stanley Dean Witter 
Short-Term Bond Fund, and in shares of five money market funds: Morgan 
Stanley Dean Witter Liquid Asset Fund Inc., Morgan Stanley Dean Witter 
Tax-Free Daily Income Trust, Morgan Stanley Dean Witter California Tax-Free 
Daily Income Trust, Morgan Stanley Dean Witter New York Municipal Money 
Market Trust, or Morgan Stanley Dean Witter U.S. Government Money Market 
Trust (these nine funds, including the Fund, are hereinafter collectively 
referred to as "Exchange Funds"). There is no waiting period for exchanges of 
shares acquired by exchange or dividend reinvestment. Shares of the Exchange 
Funds received in an exchange for shares of a Morgan Stanley Dean Witter 
Multi-Class Fund may be redeemed and exchanged only for shares of the 
corresponding Class of a Morgan Stanley Dean Witter Multi-Class Fund or for 
shares of one of the other Exchange Funds, provided that shares of the 
Exchange Funds received in an exchange for Class A shares of a Morgan Stanley
Dean Witter Multi-Class Fund may also be redeemed and exchanged for shares of a
FSC Fund, and shares of the Exchange Funds received in an exchange for Class B 
shares of a Morgan Stanley Dean Witter Multi-Class Fund may also be redeemed 
and exchanged for shares of a Global Short-Term. In addition, shares of the 
Exchange Funds received in an exchange for shares of a FSC Fund may be 
redeemed and exchanged for Class A shares of a Morgan Stanley Dean Witter 
Multi-Class Fund or for shares of one of the other Exchange Funds, and shares 
of the Exchange Funds received in an exchange for shares of a Global 
Short-Term may be redeemed and exchanged for Class B shares of a Morgan 
Stanley Dean Witter Multi-Class Fund or for shares of one of the other 
Exchange Funds. Ultimately, any applicable CDSC will have to be paid upon 
redemption of shares originally purchased from Global Short-Term or a Class 
of a Morgan Stanley Dean Witter Multi-Class Fund that imposes a CDSC. An 
exchange will be treated for federal income tax purposes the same as a 
repurchase or redemption of shares, on which the shareholder may realize a 
capital gain or loss. 


   Any new account established through the Exchange Privilege will have the 
same registration and cash dividend or dividend reinvestment plan as the 
present account, unless the Transfer Agent receives written notification to 
the contrary. For telephone exchanges, the exact registration of the existing 
account and the account number must be provided. 

   Any shares held in certificate form cannot be exchanged but must be 
forwarded to the Transfer Agent and deposited into the shareholder's account 
before being eligible for exchange. (Certificates mailed in for deposit 
should not be endorsed.) 


   When shares of a Morgan Stanley Dean Witter Multi-Class Fund or Global 
Short-Term are exchanged for shares of any Exchange Fund, the exchange is 
executed at no charge to the shareholder, without the imposition of the CDSC 
at the time of the exchange. During the period of time the shareholder 
remains in the Exchange Fund (calculated from the last day of the month in 
which the Exchange Fund shares were acquired), the holding period or "year 
since purchase payment made" is frozen. When shares are redeemed out of the 
Exchange Fund, they will be subject to a CDSC which would be based upon the 
period of time the shareholder held shares in a Morgan Stanley Dean Witter 
Multi-Class Fund or in Global Short-Term. However, in the case of shares 
exchanged into the Exchange Fund on or after April 23, 1990, upon redemption 
of shares which results in a CDSC being imposed, a credit (not to 

                                       28
<PAGE>


exceed the amount of the CDSC) will be given in an amount equal to the 
Exchange Fund 12b-1 distribution fees, if any, incurred on or after that date 
which are attributable to those shares. Shareholders acquiring shares of an 
Exchange Fund pursuant to this exchange privilege may exchange those shares 
back into a Morgan Stanley Dean Witter Multi-Class Fund or Global Short-Term 
from the Exchange Fund, with no CDSC being imposed on such exchange. The 
holding period previously frozen when shares were first exchanged for shares 
of the Exchange Fund resumes on the last day of the month in which shares of 
a Morgan Stanley Dean Witter Multi-Class Fund or of Global Short-Term are 
reacquired. Thus, a CDSC is imposed only upon an ultimate redemption, based 
upon the time (calculated as described above) the shareholder was invested in 
a Morgan Stanley Dean Witter Multi-Class Fund or in Global Short-Term. In the 
case of exchanges of Class A shares of a Morgan Stanley Dean Witter 
Multi-Class Fund which are subject to a CDSC, the holding period also 
includes the time (calculated as described above) the shareholder was 
invested in a FSC Fund. 

   When shares initially purchased in a Morgan Stanley Dean Witter 
Multi-Class Fund or in Global Short-Term are exchanged for shares of a Morgan 
Stanley Dean Witter Multi-Class Fund, shares of Global Short-Term, shares of 
a FSC Fund, or shares of an Exchange Fund, the date of purchase of the shares 
of the fund exchanged into, for purposes of the CDSC upon redemption, will be 
the last day of the month in which the shares being exchanged were originally 
purchased. In allocating the purchase payments between funds for purposes of 
the CDSC, the amount which represents the current net asset value of shares 
at the time of the exchange which were (i) purchased more than one, three or 
six years (depending on the CDSC schedule applicable to the shares) prior to 
the exchange, (ii) originally acquired through reinvestment of dividends or 
distributions and (iii) acquired in exchange for shares of FSC Funds, or for 
shares of other Morgan Stanley Dean Witter Funds for which shares of FSC 
Funds have been exchanged (all such shares called "Free Shares"), will be 
exchanged first. After an exchange, all dividends earned on shares in the 
Exchange Fund will be considered Free Shares. If the exchanged amount exceeds 
the value of such Free Shares, an exchange is made, on a block-by-block 
basis, of non-Free Shares held for the longest period of time (except that if 
shares held for identical periods of time but subject to different CDSC 
schedules are held in the same Exchange Privilege account, the shares of that 
block that are subject to a lower CDSC rate will be exchanged prior to the 
shares of that block that are subject to a higher CDSC rate). Shares equal to 
any appreciation in the value of non-Free Shares exchanged will be treated as 
Free Shares, and the amount of the purchase payments for the non-Free Shares 
of the fund exchanged into will be equal to the lesser of (a) the purchase 
payments for, or (b) the current net asset value of, the exchanged non-Free 
Shares. If an exchange between funds would result in exchange of only part of 
a particular block of non-Free Shares, then shares equal to any appreciation 
in the value of the block (up to the amount of the exchange) will be treated 
as Free Shares and exchanged first, and the purchase payment for that block 
will be allocated on a pro rata basis between the non-Free Shares of that 
block to be retained and the non-Free Shares to be exchanged. The prorated 
amount of such purchase payment attributable to the retained non-Free Shares 
will remain as the purchase payment for such shares, and the amount of 
purchase payment for the exchanged non-Free Shares will be equal to the 
lesser of (a) the prorated amount of the purchase payment for, or (b) the 
current net asset value of, those exchanged non-Free Shares. Based upon the 
procedures described in the Morgan Stanley Dean Witter Multi-Class Fund 
Prospectus under the caption "Purchase of Fund Shares" and in the Global 
Short-Term Prospectus under the caption "Contingent Deferred Sales Charge," 
any applicable CDSC will be imposed upon the ultimate redemption of shares of 
any fund, regardless of the number of exchanges since those shares were 
originally purchased. 


   With respect to the redemption or repurchase of shares of the Fund, the 
application of proceeds to the purchase of new shares in the Fund or any 
other of the funds and the general administration of the Exchange Privilege, 
the Transfer Agent acts as agent for the Distributor and for the 
shareholder's selected broker-dealer, if any, in the performance of such 
functions. With respect to exchanges, redemptions or repurchases, the 
Transfer Agent shall be liable for its own negligence and not for the default 
or negligence of its correspondents or for losses in transit. The Fund shall 
not be liable for any default or negligence of the Transfer Agent, the 
Distributor or any selected broker-dealer. 

   The Distributor and any selected broker-dealer have authorized and 
appointed the Transfer Agent to act as their agent in connection with the 
application of proceeds of any redemption of Fund shares to 

                                       29
<PAGE>

the purchase of the shares of any other fund and the general administration 
of the Exchange Privilege. No commission or discounts will be paid to the 
Distributor or any selected broker-dealer for any transactions pursuant to 
this Exchange Privilege. 

   Shares of the Fund acquired pursuant to the Exchange Privilege will be 
held by the Fund's Transfer Agent in an Exchange Privilege account distinct 
from any account of the same shareholder who may have acquired shares of the 
Fund directly. A shareholder of the Fund will not be permitted to make 
additional investments in such Exchange Privilege account, except through the 
exchange of additional shares of the fund in which the shareholder had 
initially invested, and the proceeds of any shares redeemed from such 
Exchange Privilege account may not thereafter be placed back into that 
Exchange Privilege account, except by utilizing the Reinstatement Privilege 
(see "Redemptions and Repurchases--Reinstatement Privilege"). If such a 
shareholder desires to make any additional investments in the Fund, a 
separate account will be maintained for receipt of such investments. The Fund 
will have additional costs for account maintenance if a shareholder has more 
than one account with the Fund. 


   Exchanges are subject to the minimum investment requirement and any other 
conditions imposed by each fund. (The minimum initial investment for the 
Exchange Privilege account of each Class is $10,000 for the Fund (although 
the Fund, in its discretion, may accept initial investments of as low as 
$5,000) and $5,000 for Morgan Stanley Dean Witter Liquid Asset Fund Inc., 
Morgan Stanley Dean Witter Tax-Free Daily Income Trust, Morgan Stanley Dean 
Witter California Tax-Free Daily Income Trust, and Morgan Stanley Dean Witter 
New York Municipal Money Market Trust, although those funds may, at their 
discretion, accept initial investments of as low as $1,000. The minimum 
initial investment for the Exchange Privilege account of each Class is $5,000 
for Morgan Stanley Dean Witter Special Value Fund. The minimum initial 
investment for the Exchange Privilege account of each Class of all other 
Morgan Stanley Dean Witter Funds for which the Exchange Privilege is 
available is $1,000.) Upon exchange into an Exchange Fund, the shares of that 
fund will be held in a special Exchange Privilege account separately from 
accounts of those shareholders who have acquired their shares directly from 
that fund. As a result, certain services normally available to shareholders 
of the Fund or of money market funds, including the check writing feature, 
will not be available for funds held in that account. 

   The Fund and each of the other Morgan Stanley Dean Witter Funds may limit 
the number of times this Exchange Privilege may be exercised by any investor 
within a specified period of time. Also, the Exchange Privilege may be 
terminated or revised at any time by any of the Morgan Stanley Dean Witter 
Funds, upon such notice as may be required by applicable regulatory agencies 
(presently sixty days' prior written notice for termination or material 
revision), provided that six months' prior written notice of termination will 
be given to the shareholders who hold shares of Exchange Funds pursuant to 
this Exchange Privilege, and provided further that the Exchange Privilege may 
be terminated or materially revised at times (a) when the New York Stock 
Exchange is closed for other than customary weekends and holidays, (b) when 
trading on that Exchange is restricted, (c) when an emergency exists as a 
result of which disposal by the Fund of securities owned by it is not 
reasonably practicable or it is not reasonably practicable for the Fund 
fairly to determine the value of its net assets, (d) during any other period 
when the Securities and Exchange Commission by order so permits (provided 
that applicable rules and regulations of the Securities and Exchange 
Commission shall govern as to whether the conditions prescribed in (b) or (c) 
exist), or (e), if the Fund would be unable to invest amounts effectively in 
accordance with its investment objective(s), policies and restrictions. 

   For further information regarding the Exchange Privilege, shareholders 
should contact their Morgan Stanley Dean Witter Financial Advisor or other 
Selected Broker-Dealer representative or the Transfer Agent. 


REDEMPTIONS AND REPURCHASES 
- ----------------------------------------------------------------------------- 

   Payment for Shares Redeemed or Repurchased. As discussed in the 
Prospectus, payment for shares presented for repurchase or redemption will be 
made by check within seven days after receipt by the Transfer Agent of the 
certificate and/or written request in good order. The term "good order" means 

                                      30
<PAGE>


that the share certificate, if any, and request for redemption, are properly 
signed, accompanied by any documentation required by the Transfer Agent, and 
bear signature guarantees when required by the Fund or the Transfer Agent. 
Such payment may be postponed or the right of redemption suspended at times 
(a) when the New York Stock Exchange is closed for other than customary 
weekends and holidays, (b) when trading on that Exchange is restricted, (c) 
when an emergency exists as a result of which disposal by the Fund of 
securities owned by it is not reasonably practicable or it is not reasonably 
practicable for the Fund fairly to determine the value of its net assets, or 
(d) during any other period when the Securities and Exchange Commission by 
order so permits; provided that applicable rules and regulations of the 
Securities and Exchange Commission shall govern as to whether the conditions 
prescribed in (b) or (c) exist. If the shares to be redeemed have recently 
been purchased by check (including a certified check or bank cashier's 
check), payment of the redemption proceeds may be delayed for the minimum 
time needed to verify that the check used for investment has been honored 
(not more than fifteen days from the time of receipt of the check by the 
Transfer Agent). It has been and remains the Fund's policy and practice that, 
if checks for redemption proceeds remain uncashed, no interest will accrue on 
amounts represented by such uncashed checks. Shareholders maintaining margin 
accounts with DWR or another Selected Broker-Dealer are referred to their 
Morgan Stanley Dean Witter Financial Advisor or other Selected Broker-Dealer 
representative regarding restrictions on redemption of shares of the Fund 
pledged in the margin account. 


   Involuntary Redemption. As described in the Prospectus, due to the 
relatively high cost of handling small investments, the Fund reserves the 
right to redeem, at net asset value, the shares of any shareholder whose 
shares have a value of less than $100, or such lesser amount as may be fixed 
by the Board of Trustees. However, before the Fund redeems such shares and 
sends the proceeds to the shareholder, it will notify the shareholder that 
the value of the shares is less than $100 and allow him or her 60 days to 
make an additional investment in an amount which will increase the value of 
his or her account to $100 or more before the redemption is processed. 


   Reinstatement Privilege. As discussed in the Prospectus, a shareholder who 
has had his or her shares redeemed or repurchased and has not previously 
exercised this reinstatement privilege may within 30 days after the date of 
redemption or repurchase reinstate any portion of all of the proceeds of such 
redemption or repurchase in shares of a Morgan Stanley Dean Witter Fund at 
the net asset value next determined after a reinstatement request, together 
with such proceeds, is received by the Transfer Agent. 

   Exercise of the reinstatement privilege will not affect the federal income 
tax treatment of any gain or loss realized upon the redemption or repurchase, 
except that if the redemption or repurchase resulted in a loss and 
reinstatement is made in shares of a Morgan Stanley Dean Witter Fund, some or 
all of the loss, depending on the amount reinstated, will not be allowed as a 
deduction for federal income tax purposes, but will be applied to adjust the 
cost basis of the shares acquired upon reinstatement. 


DIVIDENDS, DISTRIBUTIONS AND TAXES 
- ----------------------------------------------------------------------------- 

   The Fund intends to distribute substantially all of its net investment 
income and all of its net short-term capital gains, if any, and will 
determine whether to retain all or part of any net long-term capital gains 
for reinvestment. If any such gains are retained, the Fund will pay federal 
income tax thereon, and will notify shareholders that following such election 
the shareholders will be required to include such undistributed gains in 
determining their taxable income and may claim their share of the tax paid as 
a credit against their individual federal income tax (but not the personal 
income tax of a particular state). 

   As discussed in the Prospectus, the Fund may invest a portion of its 
assets in certain "private activity bonds" issued after August 7, 1986. As a 
result, a portion of the exempt-interest dividends paid by the Fund may be an 
item of tax preference to shareholders subject to the federal alternative 
minimum tax. Certain corporations which are subject to the alternative 
minimum tax may also have to include exempt-interest dividends in calculating 
their alternative minimum taxable income in situations where the "adjusted 
current earnings" of the corporation exceeds its alternative minimum taxable 
income. 

                                       31
<PAGE>

   Each shareholder will be sent a summary of his or her account, at least 
quarterly, including information as to reinvested dividends and capital gains 
distributions. Share certificates for dividends or distributions will not be 
issued unless a shareholder requests in writing that a certificate be issued 
for a specific number of shares. 

   In computing interest income, the Fund will amortize any premiums and 
original issue discounts on securities owned. Additionally, with respect to 
market discount on bonds purchased after April 30, 1993, a portion of any 
capital gain realized upon disposition is recharacterized as investment 
income. Capital gains or losses realized upon sale or maturity of such 
securities will be based on their amortized cost. 

   Gains or losses on the sales of securities by the Fund will be long-term 
capital gains or losses if the securities have been held by the Fund for more 
than twelve months. Gains or losses on the sale of securities held for twelve 
months or less will be short-term capital gains or losses. Gains and losses 
on the sale, expiration or other termination of options on securities will 
generally be treated as gains and losses from the sale of securities. 
Pursuant to present federal income tax laws, futures contracts held by the 
Fund at the end of each fiscal year will be required to be 
"marked-to-market," that is, treated as having been sold at their fair market 
value at such date. Sixty percent of any gain or loss recognized on these 
deemed sales will be treated as long-term capital gain or loss, and the 
remainder will be treated as short-term capital gain or loss. Gains or losses 
from options on futures and options on debt instruments will also generally 
be treated as part short-term and part long-term capital gains or losses, 
unless such gains or losses were incurred as part of a securities "straddle," 
in which case the appropriate straddle rules of the Internal Revenue Code 
(the "Code") would apply. 

   Because the Fund intends to distribute all of its net investment income 
and capital gains to shareholders and otherwise continue to qualify as a 
regulated investment company under Subchapter M of the Internal Revenue Code, 
it is not expected that the Fund will be required to pay any federal income 
tax. Shareholders will normally have to pay federal income taxes, and any 
applicable state and/or local income taxes, on the dividends and 
distributions they receive from the Fund. Such dividends and distributions, 
to the extent that they are derived from net investment income or short-term 
capital gains, are taxable to the shareholder as ordinary income regardless 
of whether the shareholder receives such payments in additional shares or in 
cash. Any dividends declared in the last quarter of any calendar year which 
are paid in the following calendar year prior to February 1 will be deemed 
received by the shareholder in the prior calendar year. 


   One of the requirements for regulated investment company status is that at 
least 90% of a fund's gross income be derived from dividends, interest, gains 
from the sale or other disposition of securities and certain other related 
income. Accordingly, the Fund may be restricted in the writing of options on 
securities held for less than three months, in the writing of options which 
expire in less than three months, and in effecting closing transactions with 
respect to call or put options which have been written or purchased less than 
three months prior to such transactions. The Fund may also be restricted in 
its ability to engage in transactions involving futures contracts. 


   As discussed in the Prospectus, the Fund intends to qualify to pay 
"exempt-interest dividends" to its shareholders by maintaining, as of the 
close of each quarter of its taxable year, at least 50% of the value of its 
total assets in tax-exempt securities. An exempt-interest dividend is that 
part of dividend distributions made by the Fund which consists of interest 
received by the Fund on tax-exempt securities upon which the shareholder 
incurs no federal income taxes (apart from any possible application of the 
alternative minimum tax). 

   Under the Revenue Reconciliation Act of 1993, all or a portion of the 
Fund's gain from the sale or redemption of tax-exempt obligations purchased 
at a market discount after April 30, 1993 will be treated as ordinary income 
rather than capital gain. This rule may increase the amount of ordinary 
income dividends received by shareholders. 

   The Fund will mail to shareholders a statement indicating the percentage 
of the dividend distributions for each fiscal year which constitutes 
exempt-interest dividends and the percentage, if any, that is taxable, and 
the percentage, if any, of the exempt-interest dividends which constitutes an 
item of 

                                       32
<PAGE>

tax preference, and to what extent the taxable portion is long-term capital 
gain or ordinary income. These percentages should be applied uniformly to all 
monthly distributions made during the fiscal year to determine the proportion 
of dividends that is tax-exempt. The percentages may differ from the 
percentage of tax-exempt dividend distributions for any particular month. 

   Shareholders will be subject to federal income tax on dividends paid from 
interest income derived from taxable securities and on distributions of net 
short-term capital gains. Such dividends and distributions are taxable to the 
shareholder as ordinary dividend income regardless of whether the shareholder 
receives such distributions in additional shares or in cash. Distributions of 
long-term capital gains, if any, are taxable as long-term gains, regardless 
of how long the shareholder has held Fund shares and whether the distribution 
is received in additional shares or in cash. Since the Fund's income is 
expected to be derived entirely from interest rather than dividends, none of 
such dividend distributions will be eligible for the 70% dividends received 
deduction generally available to corporations. Net long-term capital gains 
distributions are not eligible for the dividends received deduction. 

   Any loss on the sale or exchange of shares of the Fund which are held for 
six months or less is disallowed to the extent of the amount of any 
exempt-interest dividends paid with respect to such shares. Treasury 
Regulations may provide for a reduction in such required holding period. If a 
shareholder receives a distribution that is taxed as long-term capital gain 
on shares held for six months or less and then sells those shares at a loss, 
the loss will be treated as a long-term capital loss to the extent of the 
capital gains distribution. 

   Interest on indebtedness incurred or continued by a shareholder to 
purchase or carry shares of the Fund is not deductible to the extent 
allocable to exempt-interest dividends of the Fund (which allocation does not 
take into account capital gain distributions from the Fund). Furthermore, 
entities or persons who are "substantial users" (or related persons) of 
facilities financed by industrial development bonds should consult their tax 
advisers before purchasing shares of the Fund. "Substantial user" is defined 
generally by Income Tax Regulation 1.103-11 (b) as including a "non-exempt 
person" who regularly uses in a trade or business a part of a facility 
financed from the proceeds of industrial development bonds. 

   Federal Income Tax Status. From time to time, proposals have been 
introduced before Congress for the purpose of restricting or eliminating the 
federal income tax exemption for interest on municipal securities. It can be 
expected that similar proposals may be introduced in the future. If such a 
proposal were enacted, the availability of municipal securities for 
investment by the Fund could be affected. In such event, the Fund would 
re-evaluate its investment objective and policies. 


   At March 31, 1998, the Fund had an approximate net capital loss carryover 
of $8,789,000 of which $4,621,000 will be available through March 31, 2003, 
$3,941,000 will be available through March 31, 2004 and $227,000 will be 
available through March 31, 2005. To the extent that these net capital loss 
carryovers are used to offset future capital gains, it is probable that the 
gains so offset will not be distributed to shareholders. 


   Any dividends or distributions received by a shareholder from any 
investment company will have the effect of reducing the net asset value of 
the shareholder's stock in that fund by the exact amount of the dividend or 
distribution. Furthermore, capital gains distributions are, and some portion 
of the dividends may be, subject to income tax. If the net asset value of the 
shares should be reduced below a shareholder's cost as a result of the 
payment of taxable dividends or the distribution of realized long-term 
capital gains, such payment or distribution would be in part a return of 
capital but nonetheless taxable to the shareholder. Therefore, an investor 
should consider the tax implications of purchasing Fund shares immediately 
prior to a distribution record date. 

   The foregoing relates to federal income taxation in effect as of the date 
of the Prospectus. 

   The Fund is organized as a Massachusetts business trust. Under current 
law, so long as it qualifies as a "regulated investment company" under the 
Code, the Fund itself is not liable for any income or franchise tax in The 
Commonwealth of Massachusetts.

PERFORMANCE INFORMATION 
- ----------------------------------------------------------------------------- 


   As discussed in the Prospectus, from time to time the Fund may quote its 
"yield" and/or its "total return" in advertisements and sales literature. The 
yield is calculated for any 30-day period as follows: the amount of interest 
income for each security in the Fund's portfolio is determined in accordance 
with regulatory requirements; the total for the entire portfolio constitutes 
the Fund's gross income for the period. Expenses accrued during the period 
are subtracted to arrive at "net investment income". The resulting amount is 
divided by the product of the net asset value per share of the Fund on the 
last day of the period multiplied by the average number of shares outstanding 
during the period that were entitled to dividends. This amount is added to 1 
and raised to the sixth power. 1 is then subtracted from the result and the 
difference is multiplied by 2 to arrive at the annualized yield. Based on the 
foregoing calculation, the Fund's annualized yield for the thirty (30) day 
period ending March 31, 1998 was 3.40%. 

   To determine interest income from debt obligations, a yield-to-maturity, 
expressed as a percentage, is determined for obligations held at the 
beginning of the period, based on the current market value of the security 
plus accrued interest, generally as of the end of the month preceding the 
30-day period, or, for obligations purchased during the period, based on the 
cost of the security (including accrued interest). The yield-to-maturity is 
multiplied by the market value (plus accrued interest) for each security and 
the result is divided by 360 and multiplied by 30 days or the number of days 
the security was held during the period, if less. Modifications are made for 
determining yield-to-maturity on certain tax-exempt securities. 

   The Fund may also quote a "tax-equivalent yield" determined by dividing 
the tax-exempt portion of the quoted yield by 1 minus the stated income tax 
rate and adding the result to the portion of the yield that is not 
tax-exempt. Based on the foregoing calculation and a Federal personal income 
tax bracket of 39.6%, the Fund's annualized tax-equivalent yield for the 
thirty (30) day period ending March 31, 1998 was 5.63%. 

   The Fund's "average annual total return" represents an annualization of 
the Fund's total return over a particular period and is computed by finding 
the annual percentage rate which will result in the ending redeemable value 
of a hypothetical $1,000 investment made at the beginning of a one, five or 
ten year period, or for the period from the date of commencement of the 
Fund's operations, if shorter than any of the foregoing. For the purpose of 
this calculation, it is assumed that all dividends and distributions are 
reinvested. The formula for computing the average annual total return 
involves a percentage obtained by dividing the ending redeemable value by the 
amount of the initial investment, taking a root of the quotient (where the 
root is equivalent to the number of years in the period) and subtracting 1 
from the result. Based on the foregoing calculation, the Fund's average 
annual total return for the fiscal year ended March 31, 1998 and for the 
period July 12, 1993 (commencement of operations) through March 31, 1998 was 
7.70% and 4.76%, respectively. 

   In addition to the foregoing, the Fund may advertise its total return over 
different periods of time by means of aggregate, average, year-by-year or 
other types of total return figures. In addition, the Fund may also compute 
its aggregate total return for specified periods by determining the aggregate 
percentage rate which will result in the ending value of a hypothetical 
$1,000 investment made at the beginning of the period. For the purpose of 
this calculation, it is assumed that all dividends and distributions are 
reinvested. The formula for computing aggregate total return involves a 
percentage obtained by dividing the ending value by the initial $1,000 
investment and subtracting 1 from the result. Based on the foregoing 
calculation, the Fund's aggregate total return for the fiscal year ended 
March 31, 1998 and for the period July 12, 1993 (commencement of operations) 
through March 31, 1998 was 7.70% and 24.50%, respectively. The Fund may also 
advertise the growth of hypothetical investments of $10,000, $50,000 and 
$100,000 in shares of the Fund by adding 1 to the Fund's aggregate total 
return (expressed as a decimal) and multiplying by $10,000, $50,000 or 
$100,000 as the case may be. Investments of $10,000, $50,000 and $100,000 in 
the Fund at inception would have grown to $12,450, $62,250 and $124,500, 
respectively at March 31, 1998. 

   The Fund from time to time may also advertise its performance relative to 
certain performance rankings and indices compiled by independent 
organizations.

SHARES OF THE FUND 
- ----------------------------------------------------------------------------- 


   As discussed in the Prospectus, the shareholders of the Fund are entitled 
to a full vote for each full share held. All of the Trustees have been 
elected by the shareholders of the Fund, most recently at a Special Meeting 
of Shareholders held on May 21, 1997. The Trustees themselves have the power 
to alter the number and the terms of office of the Trustees (as provided for 
in the Declaration of Trust), and they may at any time lengthen or shorten 
their own terms or make their terms of unlimited duration and appoint their 
own successors, provided that always at least a majority of the Trustees has 
been elected by the shareholders of the Fund. Under certain circumstances the 
Trustees may be removed by action of the Trustees. The shareholders also have 
the right under certain circumstances to remove the Trustees following a 
meeting called for the purpose, requested in writing by recordholders of not 
less than 10% of the Fund's outstanding shares. The voting rights of 
shareholders are not cumulative, so that holders of more than 50 percent of 
the shares voting can, if they choose, elect all Trustees being elected, 
while the holders of the remaining shares would be unable to elect any 
Trustees. 


   The Declaration of Trust permits the Trustees to authorize the creation of 
additional series of shares (the proceeds of which would be invested in 
separate, independently managed portfolios) and additional classes of shares 
within any series (which would be used to distinguish among the rights of 
different categories of shareholders.) The Trustees have not presently 
authorized any such additional series or classes of shares. 

   The Fund is not required to hold Annual Meetings of Shareholders and in 
ordinary circumstances the Fund does not intend to hold such meetings. The 
Trustees may call Special Meetings of Shareholders for action by shareholder 
vote as may be required by the Act or the Declaration of Trust. 

   The Declaration of Trust further provides that no Trustee, officer, 
employee or agent of the Fund is liable to the Fund or to a shareholder, nor 
is any Trustee, officer, employee or agent liable to any third persons in 
connection with the affairs of the Fund, except as such liability may arise 
from his/her or its own bad faith, willful misfeasance, gross negligence, or 
reckless disregard of his/her or its duties. It also provides that all third 
persons shall look solely to the Fund's property for satisfaction of claims 
arising in connection with the affairs of the Fund. With the exceptions 
stated, the Declaration of Trust provides that a Trustee, officer, employee 
or agent is entitled to be indemnified against all liability in connection 
with the affairs of the Fund. 

   The Fund shall be of unlimited duration subject to the provisions in the 
Declaration of Trust concerning termination by action of the shareholders.

DEAN WITTER LIMITED TERM MUNICIPAL TRUST 
NOTES TO FINANCIAL STATEMENTS March 31, 1998 


1. ORGANIZATION AND ACCOUNTING POLICIES 


Dean Witter Limited Term Municipal Trust (the "Fund") is registered under the 
Investment Company Act of 1940, as amended, as a diversified, open-end 
management investment company. The Fund's investment objective is to provide 
a high level of current income which is exempt from federal income tax, 
consistent with the preservation of capital and prescribed standards of 
quality and maturity. The Fund seeks to achieve this objective by investing 
primarily in intermediate term, investment grade municipal securities. The 
Fund was organized as a Massachusetts business trust on February 25, 1993 and 
commenced operations on July 12, 1993. 


The preparation of financial statements in accordance with generally accepted 
accounting principles requires management to make estimates and assumptions 
that affect the reported amounts and disclosures. Actual results could differ 
from those estimates. 

The following is a summary of significant accounting policies: 

A. VALUATION OF INVESTMENTS-- Portfolio securities are valued by an outside 
independent pricing service approved by the Trustees. The pricing service has 
informed the Fund that in valuing the portfolio securities, it uses both a 
computerized matrix of tax-exempt securities and evaluations by its staff, in 
each case based on information concerning market transactions and quotations 
from dealers which reflect the bid side of the market each day. The portfolio 
securities are thus valued by reference to a combination of transactions and 
quotations for the same or other securities believed to be comparable in 
quality, coupon, maturity, type of issue, call provisions, trading 
characteristics and other features deemed to be relevant. Short-term debt 
securities having a maturity date of more than sixty days at time of purchase 
are valued on a mark-to-market basis until sixty days prior to maturity and 
thereafter at amortized cost based on their value on the 61st day. Short-term 
debt securities having a maturity date of sixty days or less at the time of 
purchase are valued at amortized cost. 

B. ACCOUNTING FOR INVESTMENTS-- Security transactions are accounted for on 
the trade date (date the order to buy or sell is executed). Realized gains 
and losses on security transactions are determined by the identified cost 
method. Discounts are accreted and premiums are amortized over the life of 
the respective securities. Interest income is accrued daily. 

C. FEDERAL INCOME TAX STATUS-- It is the Fund's policy to comply with the 
requirements of the Internal Revenue Code applicable to regulated investment 
companies and to distribute all of its taxable and nontaxable income to its 
shareholders. Accordingly, no federal income tax provision is required. 

                                      44

DEAN WITTER LIMITED TERM MUNICIPAL TRUST 
NOTES TO FINANCIAL STATEMENTS March 31, 1998, continued 


D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS-- The Fund records dividends 
and distributions to its shareholders on the record date. The amount of 
dividends and distributions from net investment income and net realized 
capital gains are determined in accordance with federal income tax 
regulations which may differ from generally accepted accounting principles. 
These "book/tax" differences are either considered temporary or permanent in 
nature. To the extent these differences are permanent in nature, such amounts 
are reclassified within the capital accounts based on their federal tax-basis 
treatment; temporary differences do not require reclassification. Dividends 
and distributions which exceed net investment income and net realized capital 
gains for financial reporting purposes but not for tax purposes are reported 
as dividends in excess of net investment income or distributions in excess of 
net realized capital gains. To the extent they exceed net investment income 
and net realized capital gains for tax purposes, they are reported as 
distributions of paid-in-capital. 


E. ORGANIZATIONAL EXPENSES-- Dean Witter InterCapital Inc. (the "Investment 
Manager") paid the organizational expenses of the Fund in the amount of 
$141,529 which were reimbursed exclusive of $12,651 which was absorbed by the 
Investment Manager. Such expenses have been deferred and are being amortized 
by the straight-line method over a period not to exceed five years from the 
commencement of operations. 


2. INVESTMENT MANAGEMENT AGREEMENT 

Pursuant to an Investment Management Agreement, the Fund pays the Investment 
Manager a management fee, accrued daily and payable monthly, by applying the 
annual rate of 0.50% to the Fund's net assets determined as of the close of 
each business day. 

Under the terms of the Agreement, in addition to managing the Fund's 
investments, the Investment Manager maintains certain of the Fund's books and 
records and furnishes, at its own expense, office space, facilities, 
equipment, clerical, bookkeeping and certain legal services and pays the 
salaries of all personnel, including officers of the Fund who are employees 
of the Investment Manager. The Investment Manager also bears the cost of 
telephone services, heat, light, power and other utilities provided to the 
Fund. 

3. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES 

The proceeds from sales of portfolio securities, excluding short-term 
investments, for the year ended March 31, 1998 aggregated $5,532,680.

Morgan Stanley Dean Witter Trust FSB, an affiliate of the Investment Manager, 
is the Fund's transfer agent. At March 31, 1998, the Fund had transfer agent 
fees and expenses payable of approximately $600. 

The Fund has an unfunded noncontributory defined benefit pension plan 
covering all independent Trustees of the Fund who will have served as 
independent Trustees for at least five years at the time of retirement. 
Benefits under this plan are based on years of service and compensation 
during the last five years of service. Aggregate pension costs for the year 
ended March 31, 1998 included in Trustees' fees and expenses in the Statement 
of Operations amounted to $5,871. At March 31, 1998, the Fund had an accrued 
pension liability of $25,014 which is included in accrued expenses in the 
Statement of Assets and Liabilities.

DEAN WITTER LIMITED TERM MUNICIPAL TRUST 
REPORT OF INDEPENDENT ACCOUNTANTS 


TO THE SHAREHOLDERS AND TRUSTEES 
OF DEAN WITTER LIMITED TERM MUNICIPAL TRUST 

In our opinion, the accompanying statement of assets and liabilities, 
including the portfolio of investments, and the related statements of 
operations and of changes in net assets and the financial highlights present 
fairly, in all material respects, the financial position of Dean Witter 
Limited Term Municipal Trust (the "Fund") at March 31, 1998, the results of 
its operations for the year then ended, the changes in its net assets for 
each of the two years in the period then ended and the financial highlights 
for each of the four years in the period then ended and for the period July 
12, 1993 (commencement of operations) through March 31, 1994, in conformity 
with generally accepted accounting principles. These financial statements and 
financial highlights (hereafter referred to as "financial statements") are 
the responsibility of the Fund's management; our responsibility is to express 
an opinion on these financial statements based on our audits. We conducted 
our audits of these financial statements in accordance with generally 
accepted auditing standards which require that we plan and perform the audit 
to obtain reasonable assurance about whether the financial statements are 
free of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements, 
assessing the accounting principles used and significant estimates made by 
management, and evaluating the overall financial statement presentation. We 
believe that our audits, which included confirmation of securities at March 
31, 1998 by correspondence with the custodian, provide a reasonable basis for 
the opinion expressed above.

RATINGS OF INVESTMENTS 

MOODY'S INVESTORS SERVICE INC. ("MOODY'S") 

                            MUNICIPAL BOND RATINGS 

<TABLE>
<CAPTION>
<S>      <C>
Aaa      Bonds which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment 
         risk and are generally referred to as "gilt edge." Interest payments are protected by a large or by an 
         exceptionally stable margin and principal is secure. While the various protective elements are likely to 
         change, such changes as can be visualized are most unlikely to impair the fundamentally strong position 
         of such issues. 

Aa       Bonds which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group 
         they comprise what are generally known as high grade bonds. They are rated lower than the best bonds because 
         margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may 
         be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat 
         larger than in Aaa securities. 

A        Bonds which are rated A possess many favorable investment attributes and are to be considered as upper 
         medium grade obligations. Factors giving security to principal and interest are considered adequate, but 
         elements may be present which suggest a susceptibility to impairment sometime in the future. 

Baa      Bonds which are rated Baa are considered as medium grade obligation; i.e., they are neither highly protected 
         nor poorly secured. Interest payments and principal security appear adequate for the present but certain 
         protective elements may be lacking or may be characteristically unreliable over any great length of time. 
         Such bonds lack outstanding investment characteristics and in fact have speculative characteristics as 
         well. 

         Bonds rated Aaa, Aa, A and Baa are considered investment grade bonds. 

Ba       Bonds which are rated Ba are judged to have speculative elements; their future cannot be considered as 
         well assured. Often the protection of interest and principal payments may be very moderate, and therefore 
         not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes 
         bonds in this class. 

B        Bonds which are rated B generally lack characteristics of the desirable investment. Assurance of interest 
         and principal payments or of maintenance of other terms of the contract over any long period of time may 
         be small. 

Caa      Bonds which are rated Caa are of poor standing. Such issues may be in default or there may be present elements 
         of danger with respect to principal or interest. 

Ca       Bonds which are rated Ca present obligations which are speculative in a high degree. Such issues are often 
         in default or have other marked shortcomings. 

C        Bonds which are rated C are the lowest rated class of bonds, and issues so rated can be regarded as having 
         extremely poor prospects of ever attaining any real investment standing. 
</TABLE>

   Conditional Rating: Bonds for which the security depends upon the 
completion of some act of the fulfillment of some condition are rated 
conditionally. These are bonds secured by (a) earnings of projects under 
construction, (b) earnings of projects unseasoned in operation experience, 
(c) rentals which begin when facilities are completed, or (d) payments to 
which some other limiting condition attaches. Parenthetical rating denotes 
probable credit stature upon completion of construction or elimination of 
basis of condition. 

   Rating Refinements: Moody's may apply numerical modifiers, 1, 2 and 3 in 
each generic rating classification from Aa through B in its municipal bond 
rating system. The modifier 1 indicates a mid-range ranking; and a modifier 3 
indicates that the issue ranks in the lower end of its generic rating 
category.

                            MUNICIPAL NOTE RATINGS 

   Moody's ratings for state and municipal notes and other short-term loans 
are designated Moody's Investment Grade (MIG). MIG 1 denotes best quality and 
means there is present strong protection from established cash flows, 
superior liquidity support or demonstrated broad-based access to the market 
for refinancing. MIG 2 denotes high quality and means that margins of 
protection are ample although not as large as in MIG 1. MIG 3 denotes 
favorable quality and means that all security elements are accounted for but 
that the undeniable strength of the previous grades, MIG 1 and MIG 2, is 
lacking. MIG 4 denotes adequate quality and means that the protection 
commonly regarded as required of an investment security is present and that 
while the notes are not distinctly or predominantly speculative, there is 
specific risk. 

                       VARIABLE RATE DEMAND OBLIGATIONS 

   A short-term rating, in addition to the Bond or MIG ratings, designated 
VMIG may also be assigned to an issue having a demand feature. The assignment 
of the VMIG symbol reflects such characteristics as payment upon periodic 
demand rather than fixed maturity dates and payment relying on external 
liquidity. The VMIG rating criteria are identical to the MIG criteria 
discussed above. 

                           COMMERCIAL PAPER RATINGS 

   Moody's Commercial Paper ratings are opinions of the ability to repay 
punctually promissory obligations not having an original maturity in excess 
of nine months. These ratings apply to Municipal commercial Paper as well as 
taxable Commercial Paper. Moody's employs the following three designations, 
all judged to be investment grade, to indicate the relative repayment 
capacity of rated issuers: Prime-1, Prime-2, Prime-3. 

   Issuers rated Prime-1 have a superior capacity for repayment of short-term 
promissory obligations. Issuers rated Prime-2 have a strong capacity for 
repayment of short-term promissory obligations; and Issuers rated Prime-3 
have an acceptable capacity for repayment of short-term promissory 
obligations. Issuers rated Not Prime do not fall within any of the Prime 
rating categories. 

STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S") 

                            MUNICIPAL BOND RATINGS 

   A Standard & Poor's municipal rating is a current assessment of the 
creditworthiness of an obligor with respect to a specific obligation. This 
assessment may take into consideration obligors such as guarantors, insurers, 
or lessees. 

   The ratings are based on current information furnished by the issuer or 
obtained by Standard & Poor's from other sources it considers reliable. The 
ratings are based, in varying degrees, on the following considerations: (1) 
likelihood of default-capacity and willingness of the obligor as to the 
timely payment of interest and repayment of principal in accordance with the 
terms of the obligation; (2) nature of and provisions of the obligation; and 
(3) protection afforded by, and relative position of, the obligation in the 
event of bankruptcy, reorganization or other arrangement under the laws of 
bankruptcy and other laws affecting creditors' rights. 

   Standard & Poor's does not perform an audit in connection with any rating 
and may, on occasion, rely on unaudited financial information. The ratings 
may be changed, suspended or withdrawn as a result of changes in, or 
unavailability of, such information, or for other reasons. 

<TABLE>
<CAPTION>
<S>      <C>
AAA      Debt rated "AAA" has the highest rating assigned by Standard & Poor's. Capacity to pay interest and repay 
         principal is extremely strong. 

AA       Debt rated "AA" has a very strong capacity to pay interest and repay principal and differs from the highest-rated 
         issues only in small degree. 

                                       50
<PAGE>

A        Debt rated "A" has a strong capacity to pay interest and repay principal although they are somewhat more susceptible 
         to the adverse effects of changes in circumstances and economic conditions than debt in higher-rated categories. 

BBB      Debt rated "BBB" is regarded as having an adequate capacity to pay interest and repay principal. Whereas it 
         normally exhibits adequate protection parameters, adverse economic conditions or changing circumstances are 
         more likely to lead to a weakened capacity to pay interest and repay principal for debt in this category than 
         for debt in higher-rated categories. 

         Bonds rated AAA, AA, A and BBB are considered investment grade bonds. 

BB       Debt rated "BB" has less near-term vulnerability to default than other speculative grade debt. However, it 
         faces major ongoing uncertainties or exposure to adverse business, financial or economic conditions which 
         could lead to inadequate capacity to meet timely interest and principal payment. 

B        Debt rated "B" has a greater vulnerability to default but presently has the capacity to meet interest payments 
         and principal repayments. Adverse business, financial or economic conditions would likely impair capacity 
         or willingness to pay interest and repay principal. 

CCC      Debt rated "CCC" has a current identifiable vulnerability to default, and is dependent upon favorable business, 
         financial and economic conditions to meet timely payments of interest and repayments of principal. In the 
         event of adverse business, financial or economic conditions, it is not likely to have the capacity to pay 
         interest and repay principal. 

CC       The rating "CC" is typically applied to debt subordinated to senior debt which is assigned an actual or implied 
         "CCC" rating. 

C        The rating "C" is typically applied to debt subordinated to senior debt which is assigned an actual or implied 
         "CCC" debt rating. 

Cl       The rating "Cl" is reserved for income bonds on which no interest is being paid. 

D        Debt rated "D" is in payment default. The 'D' rating category is used when interest payments or principal 
         payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes 
         that such payments will be made during such grace period. The 'D' rating also will be used upon the filing 
         of a bankruptcy petition if debt service payments are jeopardized. 

NR       Indicates that no rating has been requested, that there is insufficient information on which to base a rating 
         or that Standard & Poor's does not rate a particular type of obligation as a matter of policy. 
         Bonds rated "BB", "B", "CCC", "CC" and "C" are regarded as having predominantly speculative characteristics 
         with respect to capacity to pay interest and repay principal. "BB" indicates the least degree of speculation 
         and "C" the highest degree of speculation. While such debt will likely have some quality and protective characteristics, 
         these are outweighed by large uncertainties or major risk exposures to adverse conditions. 

         Plus (+) or minus (-): The ratings from "AA" to "CCC" may be modified by the addition of a plus or minus sign 
         to show relative standing within the major ratings categories. 

         The foregoing ratings are sometimes followed by a "p" which indicates that the rating is provisional. A provisional 
         rating assumes the successful completion of the project being financed by the bonds being rated and indicates 
         that payment of debt service requirements is largely or entirely dependent upon the successful and timely 
         completion of the project. This rating, however, while addressing credit quality subsequent to completion 
         of the project, makes no comment on the likelihood or risk of default upon failure of such completion.

                            MUNICIPAL NOTE RATINGS 

   Commencing on July 27, 1984, Standard & Poor's instituted a new rating 
category with respect to certain municipal note issues with a maturity of 
less than three years. The new note ratings denote the following: 

   SP-1 denotes a very strong or strong capacity to pay principal and 
        interest. Issues determined to possess overwhelming safety 
        characteristics are given a plus (+) designation (SP-1+). 

   SP-2 denotes a satisfactory capacity to pay principal and interest. 

   SP-3 denotes a speculative capacity to pay principal and interest. 

                           COMMERCIAL PAPER RATINGS 

   Standard and Poor's commerical paper rating is a current assessment of the 
likelihood of timely payment of debt having an original maturity of no more 
than 365 days. The commercial paper rating is not a recommendation to 
purchase or sell a security. The ratings are based upon current information 
furnished by the issuer or obtained by S&P from other sources it considers 
reliable. The ratings may be changed, suspended, or withdrawn as a result of 
changes in or unavailability of such information. Ratings are graded into 
group categories, ranging from "A" for the highest quality obligations to "D" 
for the lowest. Ratings are applicable to both taxable and tax-exempt 
commercial paper. The categories are as follows: 

   Issues assigned A ratings are regarded as having the greatest capacity for 
timely payment. Issues in this category are further refined with the 
designation 1, 2 and 3 to indicate the relative degree of safety. 

A-1 indicates that the degree of safety regarding timely payments is very 
    strong. 

A-2 indicates capacity for timely payment on issues with this designation is 
    strong. However, the relative degree of safety is not as overwhelming as 
    for issues designated "A-1". 

A-3 indicates a satisfactory capacity for timely payment. Obligations 
    carrying this designation are, however, somewhat more vulnerable to the 
    adverse effects of changes in circumstances than obligations carrying the 
    higher designations.
